Primary Examiner-John M. Ford Att0meyBurgess, Dinklage & Sprung  ABSTRACT Novel halophenoxy-s-triazine derivatives and salts The novel triazine derivatives and their salts are suita ble for use as water repellants, parting agents, textile adjuvants, as fire retardants, fungicidal, phytotoxic,
bactericidal and insecticidal agents.
10 Claims, No Drawings HALOGENPHENOXY-S-TRIAZINE DERIVATIVES Where, in the above set out formula R is HAVING IMPROVED SOLUBILITY This invention relates to halogenphenoxy-s-triazine derivatives having improved solubility characteristics.
According to the present invention there is provided a novel group of halogenphenoxy-s-triazine derivatives which have the formula:-
wherein X represents from one halogen or an amino group of the formula:-
in which R represents alkyl, halogenated alkyl, alkali metal, or ammonium, R represents hydrogen, alkyl containing two to 18 carbon atoms, halogenated alkyl containing two to 18 carbon atoms or cycloalkyl and R represents alkyl, containing two to 18 carbon atoms, halogenated alkyl containing two to 18 carbon atoms, cycloalkyl or aryl and wherein R and R taken together can form a heterocyclic ring.
The novel derivatives of the invention are characterized in that they are soluble in organic solvents. The highly chlorinated halogenphenoxy-s-triazines which have heretofore been available and particularly those containing the pentachlorophenoxy group, exhibit only a very slight solubility in organic solvents.
In accordance with the invention it has been found that the solubility in organic solvents is considerably improved by replacing the halogen atoms in carbonhalogenated halogenphenoxy-s-triazines, i.e., those which still contain reactive halogen atoms, with the above-defined moiety R Thus for example, 2-chloro- 4,6-di-(pentachlorophenoxy)-s-triazine, which has a melting point of 327 C is substantially insoluble in nearly all organic solvents, while 2-phosphonic acid diethylester4,6-di-(pentachlorophenoxy)-s-triazine is readily soluble in aromatic and chlorinated hydrocarbons. This can be seen from the following Table. The compatibility of the triazine compounds with aromatic solvents is of great importance in practice.
Comparison of solubility in various organic solvents at 25C of compounds a and b in grams per 100 milliliters.
the preparation of the new triazine compounds is carried out by reacting a halogenphenoxy-s-triazine with a phosphorus acid ester at a temperature between 50 C. and 250 C and preferably at a temperature of from C to 200 C. The re-esterification can be carried out both in the fused state and with an organic solvent. The reaction temperature is increased as the reaction proceeds so that the reaction mixture is constantly boiling. Alkyl halide is split off in the reaction, and the course of the reaction can be followed on the basis of the quantity of alkyl halide that is recovered. The reaction generally requires from 1 to 6 hours. After the evolution of alkyl halide has ended, the unreacted reactants are separated off by vacuum distillation. In most instances the distillation residue is analytically pure and requires no further purification measures.
Aliphatic and aromatic hydrocarbons as well as simple and cyclic ethers are suitable as solvents for use in the reaction. It is advantageous to use not only the solvents in pure form, as for example, an aliphatic hydrocarbon compound such as isoctane, but also their mixtures can be used, such as benzine fractions, instance fractions having a boiling range of from to 200 C.
Chlorinated hydrocarbons such as dichlorothane, tetrachlorethylene, and pentachlorethane, can also be used as solvents. Benzene, toluene, o-dichlorbenzene and xylene are examples of suitable aromatic hydrocarbons. Instances of suitable ethers include: diisopropyl ether, diisoamyl ether, diphenyl ether, 1,4-dioxane etc. The above enumeration is indicative of the fact that both aliphatic and aromatic open-chain ethers can be satisfactorily used. Polar solvents such as dimethylsulfoxide, dimethylformamide, the dimethyl ether of diethylene glycol, and decaline, have also been found to be useful as solvents.
The starting materials for use in the process of the invention can be halogenated phenoxy-triazine derivatives containing reactive chlorine atoms, such as have been described in US. Pat. application Ser. No. 737129, now abandoned.
The phosphorus acid esters which can be used in the reaction with the triazine derivatives include the trialkyl phosphites in general. Lower alkyl esters of phosphorus acid, such as triethyl phosphite, tripropyl phosphite, etc., are preferred for the reaction. Halogenated trialkylphosphites, such as tris-(B- chlorethyl)-phosphite can also be advantageously used in the reaction according to the invention.
The saponification of these phosphonic acid ester derivatives with alkali to thereby form the alkali salts of phosphonic acid increases the solubility of the resulting compounds in water.
The saponification to form the salts is carried out by conventional methods, as for instance, by dissolving the phosphonic acid ester derivatives in organic solvents and heating them with an alkali.
The organic solvents which can be used for dissolv- 5 ing the phosphonic acid ester derivatives include alcohols and ketones, as for example ethanol, acetone etc., as well as the solvents mentioned heretofore in connection with the reaction of the halogenphenoxy-striazines with alkyl phosphites.
The preparation of the compounds of the invention in which R represents an amino radical, is carried out by reacting a C-chloride of a halogenated phenoxy-striazine, in the presence of a tertiary amine or of an acid amide as catalyst, at a temperature between 50 C and 250 C and preferably 80 C to 200 C, with an amine of the formula:
wherein R and R have the same significances as given above. The reaction can be conducted either with the reactants in the fused state or in an inert solvent. The inert solvent then having the function both of a genuine solvent and of a dispersing agent. The solvents which have been enumerated as suitable for use in the reaction of the halogenphenoxy-s-triazine with phosphorus acid esters can also be used for the reaction with the amine Ra H--N/ .34.
The catalysts for use in the reaction are tertiary amines having aliphatic, cycloaliphatic and aromatic radicals in which case the substituted imines are to be understood as constituting a type of cyclic tertiary amine.
Other catalysts which may be used are acid amides or N-mono or disubstituted acid amides of monobasic, aliphatic, aromatic or araliphatic carboxylic acids having one to 18 carbon atoms. These acid amides have been described for instance in US. Pat. application Ser. No. 737,129, now abandoned.
To some extent, however, the amines used for the reaction themselves serve as reaction catalysts, so that the use of a special catalyst of the kind described above can in many instances be dispensed with.
The new compounds and their salts can be used as water repellants, parting agents, dressings for glass fabrics, textile adjuvants, for the surface treatment of various materials and articles because of their fire-retardant, fungicidal, phytotoxic, bactericidal and insecticidal properties. They can also be used as additives for varnishes and enamels.
The following Examples are given for the purpose of more clearly illustrating the invention and are not to be construed as limiting.
