    摘要: A process for preparing blends or slurries of acyloxyalkane sulfonate salts is provided. The salts have the formula: R.sub.1 C(O)O(CH.sub.2).sub.n SO.sub.3 Y wherein R.sub.1 is a hydrocarbyl radical having from about 6 to about 26 carbon atoms, n is an integer of from 2 to 4 and Y is an alkali metal or alkaline earth metal. The blend also comprises an amphoteric and/or anionic surfactant. The first step of the process comprises acylating an alkane sulfonic acid with a fatty acid at a temperature above about 180.degree. C. forming a molten reaction mass of acyloxyalkane sulfonate salts. In the next step, the molten reaction mass is quenched in an aqueous quench liquid comprising an amphoteric and/or anionic surfactant. Finally, a blend comprising an acyloxyalkane sulfonate and an amphoteric and/or anionic surfactant is recovered.
