The most important fact is that it doesn't endanger and not poisoning a driver during driving, other passengers, and so it has an influence on the safety in a traffic. The other fluids (antifreezes) are carcinogenic.
STATE OF TECHNIQUE AND MARKET
There are cooling fluids which are used in the systems of cooling in internal combustion engines in open and closed systems, and doesn't freeze till the temperature from -30°C to --40°C. The most of this fluids are sold by the term Antifreeze, and the Producers in Serbia and Montenegro are: Kotrman, NIS Naftagas, Petrohemija Pancevo, in Bosnia: Optima Modrica and others, and in the world: BASF Germany, Preston America, etc.
According to our information, collected in the last ten years, through Internet and other electronic media and other information, none of the antifreezes hasn't been done on NONTOXIC base and doesn't have such a certification that it's not toxic, biodegradable, and that it doesn't pollute environment, and the technical solution has been designed on the very high level regarding anticorrosive protection of engines as well as the durability.
The defect of mentioned solutions is in the fact that they are toxic, life-time is limited on two years, insufficient inhibitor protection, poor alkali reserve, low pl-I
value about 6.2-7.2, and it should be between 9.5-11.5 according to ASTM. This invention completely meets ASTM standards.
THE COMPARATIVE ADVANTAGE
The mentioned above inventions (aqueous fluid diluted with distilled water) and as fluid concentrate in cooling systems, are consists of the following:
Cooling liquid is NONTOXIC, biodegradable, nonpoisonous and doesn't pollute environment. It's durable in cooling system (over 6 years) or 350.0001<m.
Temperature in minus till -70°C, depends of the concentration, concentration till 96%. The advantage of this patent is also in persistence of high temperature, in plus till 160°C.
Traditional cooling fluids - antifreezes with all trade names has been done on traditional base TOXIC one, mono-ethylene glycol or other glycol bases. For this invention of fluid solution there is no need for the any precautionary measures during usage and changing in engine systems. For the all other antifreezes there is an obligation of warning by law that it's TOXIC.
THE ESSENCE OF THE INVENTION
The technical problem is successfully solved by the manufacturing process of The Fo~~aulation of Nontoxic Liquid Watery Solution Against F~eezi~g and Corr°osion first of all in open and closed systems of cooling. According to this invention application, the process is performed in several phases.
First there is mixing of distilled water (soften till I level )or totally distilled, free of all minerals and pollutions with glycerol (multivalent alcohol) on 80-90°C, with constant mixing till homogenization. The ratio of a basic substance can be different,(66:34, 70:30, 80:20) it all depends of what we want to design. In ratios mentioned above it's necessary to leave a space for the inhibitor from the Formulation The Fo~~mulatio~ of Watery Solution of Inhibitor Agai>zst Corr osaofz for Utilized Antifreeze in a quantity participation of 10-20%, and then there is a continuance with heating on the same temperature and mixing till the total homogenization of product.
Against the foam, the silicate oil in small concentration of 0,004-0,009% is mostly added. Beside that, the color of high quality and also nontoxic is added, which is used in food or cosmetics. The final product is light-green liquid or heavenly blue. There is a need for adding the color in fluid so we can know that there is a liquid in the system, because, the liquid obtained on this way has white transparent color.
Besides this invention process with. adding the inhibitor which is a formulation of aqueous solution of corrosion inhibitor under The Formulation of Watery Solution of Inhibitor against corrosion for utilized antifreeze or marked in formulation under A
and B, as a explanations of detailed formulation. The problem of inhibitor protection for all the engines in which this fluid is used, is solved by usage of inhibitor which is an integral part in formulation of invention The Formulatio~z of Nontoxic Liqa~id Watery Solution Against Freezing aced Corrosion. In this way, the problem of the engine anticorrosive protection is completely solved. In this way, the nontoxic antifreeze (invention The Formulation o, f Nontoxic Liquid Watery Solution Against Freezing and Corrosion) exploitation process is enriched in all the engine systems of cooling and heating and other systems of cooling and heating.
The product obtained by this process is modified and improved with anticorrosive protection for all engines, and specially an aluminum engines and other contact metals, achieves anticorrosive protection.
The product obtained by this process, can be concentrated liquid - aqueous solution with dilution before usage according to a manufacturer instruction, as well as the aqueous solution without diluting before usage.
The invention obtained by this process is intended for open and closed systems for cooling of engine SUS, and also can be used in other systems for the heat transmission with liquid circulation, as well as the transformer of cooling and heating.
This liquid is suitable for the protection of all systems from freezing and boiling.
Especially its usage can be in food industry and nonalcoholic and alcoholic drinks industry, because, if some system damage occurs and leaking of fluid from the system, there is no danger of poising or pollution of products, as well as the environment pollution.
THE COMPARATIVE ADVANTAGE OF THIS INVENTION IN REGARD TO TI-Il:
TRADITIONAL ONES:
The fluid - antifreeze, according to this process is NONTOXIC SUBSTANCE.
Nonpoisonous is characterized in fact that it has been done on basic base of multivalent alcohol.
The main advantage of the nontoxic fluid - antifreeze on the base of multivalent alcohol (glycerol) is that the glycerol, as a dominant component, is a natural product, in contrast to other fluids against freezing, which have, as an active component, synthetic compounds - xeno-byotics, such as ethylene, propylene - glycol and mono-ethylene glycol. Nonpoisonous is confirmed by the State Institute Bavaria in Germany, as well as by analyses from the Institute in Belgrade - NU Institute for chemistry, technology and metallurgy - center for chemistry in Belgrade. This analyses proves that this patented fluid is nontoxic, nonpoisonous and doesn't pollute an environment.
The materials used for the reducing of foam and corrosion must be totally disintegrated in this product and mutually compatible. This materials, as well as the fluid itself, mustn't make sediment, be separated from the fluid or to make chemical negative reaction between them.
Something more about corrosive protection of nontoxic invention fluid:
Anticorrosive protection ~in chemical heterogenous effect has been given in average power of anticorrosive protection, keeping in mind that cooling liquid in the function of engine cooling effects on several metals, also heterogenous composition.
The inhibitor's anticorrosive protection is the solution for the modified and synthesized protection from corrosion and damage of whole cooling system of all engines, of course, beside specific and mentioned metals, it protects rubber, plastic and other hoses, asbestos, teflone parts and other gaskets, too. The inhibitor is a subject of a new technology, marked as an invention The F'o~mulatiorc o, f Water y Solution of hrhibito~ Against Co~~~osion fog Utilized Antifreeze.
Regarding the fact that the engine systems consists of several different elements, above all, copper, 2006 solder, brass, soft steel, iron and aluminum (there is increasing usage of aluminum for the modern engines), so this invention is on the base of multi-atomicity alcohol (glycerol) and has inhibitor protection by which we obtain the balance of protection of all metal elements used for the engine cooling system construction.
The advantage of the invention is that very high boiling point is achieved, depends of the basic concentration (glycerin), till 96%, for example, 1'~0°C-162°C in plus, and in minus from -4.0°C till -70°C. One more advantage of the invention is that if low temperature occurs, this fluid doesn't transfer into solid aggregate condition, but in dilapidated crystals which doesn't do any pressure on the engine walls, hoses and other, but it realizes them, and during the starting of engine they easy get warmer and start to melt without any damage of the engine and other parts of the cooling system.

THE ESSENCE OF THE INVENTION
The technical problem is successfully solved by the manufacturing process of The Fo~~aulation of Nontoxic Liquid Watery Solution Against F~eezi~g and Corr°osion first of all in open and closed systems of cooling. According to this invention application, the process is performed in several phases.
First there is mixing of distilled water (soften till I level )or totally distilled, free of all minerals and pollutions with glycerol (multivalent alcohol) on 80-90°C, with constant mixing till homogenization. The ratio of a basic substance can be different,(66:34, 70:30, 80:20) it all depends of what we want to design. In ratios mentioned above it's necessary to leave a space for the inhibitor from the Formulation The Fo~~mulatio~ of Watery Solution of Inhibitor Agai>zst Corr osaofz for Utilized Antifreeze in a quantity participation of 10-20%, and then there is a continuance with heating on the same temperature and mixing till the total homogenization of product.
Against the foam, the silicate oil in small concentration of 0,004-0,009% is mostly added. Beside that, the color of high quality and also nontoxic is added, which is used in food or cosmetics. The final product is light-green liquid or heavenly blue. There is a need for adding the color in fluid so we can know that there is a liquid in the system, because, the liquid obtained on this way has white transparent color.
Besides this invention process with. adding the inhibitor which is a formulation of aqueous solution of corrosion inhibitor under The Formulation of Watery Solution of Inhibitor against corrosion for utilized antifreeze or marked in formulation under A
and B, as a explanations of detailed formulation. The problem of inhibitor protection for all the engines in which this fluid is used, is solved by usage of inhibitor which is an integral part in formulation of invention The Formulatio~z of Nontoxic Liqa~id Watery Solution Against Freezing aced Corrosion. In this way, the problem of the engine anticorrosive protection is completely solved. In this way, the nontoxic antifreeze (invention The Formulation o, f Nontoxic Liquid Watery Solution Against Freezing and Corrosion) exploitation process is enriched in all the engine systems of cooling and heating and other systems of cooling and heating.
The product obtained by this process is modified and improved with anticorrosive protection for all engines, and specially an aluminum engines and other contact metals, achieves anticorrosive protection.
The product obtained by this process, can be concentrated liquid - aqueous solution with dilution before usage according to a manufacturer instruction, as well as the aqueous solution without diluting before usage.
The invention obtained by this process is intended for open and closed systems for cooling of engine SUS, and also can be used in other systems for the heat transmission with liquid circulation, as well as the transformer of cooling and heating.
This liquid is suitable for the protection of all systems from freezing and boiling.
Especially its usage can be in food industry and nonalcoholic and alcoholic drinks industry, because, if some system damage occurs and leaking of fluid from the system, there is no danger of poising or pollution of products, as well as the environment pollution.
THE COMPARATIVE ADVANTAGE OF THIS INVENTION IN REGARD TO TI-Il:
TRADITIONAL ONES:
The fluid - antifreeze, according to this process is NONTOXIC SUBSTANCE.
Nonpoisonous is characterized in fact that it has been done on basic base of multivalent alcohol.
The main advantage of the nontoxic fluid - antifreeze on the base of multivalent alcohol (glycerol) is that the glycerol, as a dominant component, is a natural product, in contrast to other fluids against freezing, which have, as an active component, synthetic compounds - xeno-byotics, such as ethylene, propylene - glycol and mono-ethylene glycol. Nonpoisonous is confirmed by the State Institute Bavaria in Germany, as well as by analyses from the Institute in Belgrade - NU Institute for chemistry, technology and metallurgy - center for chemistry in Belgrade. This analyses proves that this patented fluid is nontoxic, nonpoisonous and doesn't pollute an environment.
The materials used for the reducing of foam and corrosion must be totally disintegrated in this product and mutually compatible. This materials, as well as the fluid itself, mustn't make sediment, be separated from the fluid or to make chemical negative reaction between them.
Something more about corrosive protection of nontoxic invention fluid:
Anticorrosive protection ~in chemical heterogenous effect has been given in average power of anticorrosive protection, keeping in mind that cooling liquid in the function of engine cooling effects on several metals, also heterogenous composition.
The inhibitor's anticorrosive protection is the solution for the modified and synthesized protection from corrosion and damage of whole cooling system of all engines, of course, beside specific and mentioned metals, it protects rubber, plastic and other hoses, asbestos, teflone parts and other gaskets, too. The inhibitor is a subject of a new technology, marked as an invention The F'o~mulatiorc o, f Water y Solution of hrhibito~ Against Co~~~osion fog Utilized Antifreeze.
Regarding the fact that the engine systems consists of several different elements, above all, copper, 2006 solder, brass, soft steel, iron and aluminum (there is increasing usage of aluminum for the modern engines), so this invention is on the base of multi-atomicity alcohol (glycerol) and has inhibitor protection by which we obtain the balance of protection of all metal elements used for the engine cooling system construction.
The advantage of the invention is that very high boiling point is achieved, depends of the basic concentration (glycerin), till 96%, for example, 1'~0°C-162°C in plus, and in minus from -4.0°C till -70°C. One more advantage of the invention is that if low temperature occurs, this fluid doesn't transfer into solid aggregate condition, but in dilapidated crystals which doesn't do any pressure on the engine walls, hoses and other, but it realizes them, and during the starting of engine they easy get warmer and start to melt without any damage of the engine and other parts of the cooling system.

THE INHIBITOR AGAINST CORROSION OF THE SYSTEM OF COOLING AND HEATING
FOR THE UTILIZED FLUID - ANTIFREEZE IN AQUEOUS SOLUTION
The invention and a solution of the technology is the usage of concentrated inhibitor for the utilized antifreeze on nontoxic base. This is nontoxic inhibitor. Its especially advances is an efficiency, because, this inhibitor is added in a small quantities to the utilized antifreeze: This inhibitor has a big power. It regenerates utilized antifreeze, persists a high temperature of boiling, reduces freezing temperature and has a great power of anticorrosive protection of cooling and heating systems. The biggest advantage of this inhibitor is that it can be universal used in any antifreeze. It's primarily purpose is for nontoxic antifreeze against freezing and corrosion (invention The Fo~~mulatiovt of Nontoxic Liquid Watery Solutiof~ Agaif7st F~°ee~i~~g a~~d Co~yosion), but it also can be successfully used in any other antifreeze on toxic base, but then it doesn't have nontoxic meaning, but toxic, regarding to small quantity in no disintegrating antifreeze. The most significant accomplishment of this inhibitor is that it has been done with polycarboxylate, which formulation is disintegrated in alcohol, mix alcohol/water and in water..It doesn't corrode or violates cooling system, and it's effective in small quantities.
The goal of this invention is to provide formulations of concentrated inhibition of corrosion for diluted and utilized configuration of anti/ice antifreeze coolers with polymark poly-carboxylated additives, in configuration with other inhibitors which are used in this formulation, and have a great power of anticorrosive protection.
