Description

The present invention relates to liquid Detergent mixtures containing the adducts of Alkylene oxides or sulfates of the adducts contain. In particular, the present invention relates Invention liquid detergent mixtures which this Adducts or sulfates contain no odor and only a small part in aging To suffer quality loss.

Alkylene oxide adducts of hydroxyl-containing organic compounds, such as alcohols and Phenols, as well as their sulfates are called surfactants in many fields used. For example, they are used as Cleaner in industrial detergents, liquid Detergents for the household, powdery Household detergents, building detergents, Detergents for laundry and detergents for Automobiles.  

So far, the above-mentioned alkylene oxide adducts have been prepared, by alkylene oxides containing hydroxyl groups organi compounds such as alcohols and phenols in the presence of alkali catalysts such as sodium hydroxide, potassium hydroxide and sodium alkoxides or acidic catalysts such as boron trifluoride, Boron trifluoride complexes, antimony pentachloride, tin tetrachloride, Phosphoric acid, acetic acid, sulfuric acid or citric acid (US Pat. Nos. 3,030,426 and 2,983,763).

The alkylene oxide adducts prepared by this process from Hydroxyl-containing organic compounds but not only unreacted hydroxyl groups organic compounds, but also catalysts, aldehydes, free acids, peroxides and other impurities that are responsible for Odor and discoloration are responsible. The alkylene oxide adducts, which contain these impurities are neutralized with acids or alkalis, washing with aqueous alkali solutions, Purified distillation, reduction, adsorption or filtration. The alkali catalysts are generally neutralized with such neutrons  lisierungsmittel such as mineral acid (sulfuric acid or phosphorus acid) or neutralized with acetic acid. The on the above be described manner obtained Alkylenoxidaddukte contain more Contaminants responsible for the odor. you Therefore have the disadvantage that they after a certain Time to give off smell. Especially in recent times, the general My trend is the buyer for increasingly high-quality household detergentien led to the raw materials for the Detergents tried to rid themselves of the causes of the smell. The sulfonation of the Alkylenoxidaddukte, which on aging be built with such sulfonating agents as sulfur tri oxide or chlorosulfonic acid brings with it the disadvantage that the resulting sulfonation product a strong color cast shows. When the desired products are obtained by Ver use of alkylene oxide adducts produced by conventional processes, These products are far from a satisfactory condition removed, because they still contain many causes of degradation and the quality deterioration.

The alkali catalyst such as sodium hydroxide, potassium hydroxide or a sodium alkoxide used in the preparation of an alkylene oxide adduct by reaction of a hydroxyl-containing orga A compound used with an alkylene oxide is used in the generally purified by neutralization, which is effected by adding such neutralizing agents as mineral acid, for example sulfuric acid or phosphoric acid, or Acetic acid. When this neutralization is effected using tion of conventional neutralizing agents, has the Neutra lisierungsmittel the effect that the alkylene oxide adduct produced Contains components that are responsible for the release of odor or for quality deterioration in aging. The produced Alkylenoxidaddukt also has the disadvantage that the adduct, which is prepared as an aqueous solution, turbid becomes.
