PROCESS OF PREPARING SULPHONATE DERIVATIVES OF NATURAL OR SYNTHETIC TRIGLYCERIDES AND OF FAT ACID ESTERS USING HIGHER ALCOHOLS

摘要

the present invention relates to a process for obtaining derivatives of natural or synthetic sulfonaţi triglyceride fatty acids and esters to higher alcohols.and their mixtures with or without mineral oils, by sulfonating in steps of oils and fats, supplied continuously at temperatures of 40...65°c for 1 1 / 3...2 h, after which the product with sodiluat, sulfone acid degassed at a temperature of 45...60°c for 1 / 4 1 / 2 h and neutralizing continuously at 40...50 with aqueous solutions of hidroacizilor alkalis, ammonia or alcanolamine.the sulfonare reacts, leading to products with complex structures, which include hidroxisulfonaţi sulfataţi compounds and unsaturated fat, in the case of materials.- sulfocarboxilici acids or compounds of type, in the case of the saturated fatty acids (or their methyl esters).the products obtained by sulfonating with sogazos shows good hydrolytic stability in the whole field of ph, a shaft ernic degree of ionization,i'm free of alkali earth metal salts and metals are easily emulsifiable. their use may reduce the range used in fleets lubricating natural leather.
