Abstract
Process for the preparation of flowable, anhydrous acyloxyalkanesulfonates and their use In the process of the invention, in the context of the esterification of fatty acids with hydroxyalkanesulfonates, the reaction product (molten mass) at 180.degree. to 250.degree. C. is sheared in such a manner during the cooling to 150.degree. to 50.degree. C. that the mean particle size of the product is <100 .mu.m. The acyloxyalkanesulfonate product thus obtained is still highly flowable, pumpable and the like, even at temperatures in the range from 60.degree. to 100.degree. C. and be stored in the fluid state without change at these temperature even over a long period.
