Sulfoalkylating agents free from sultones may be obtained by heating hydroxy alkane sulfonic acids of propane or butane or the corresponding sultones having 5 or 6 ring members with up to four times the molar quantity of water to a temperature in the region of from 80.degree. to 180.degree. C. The sulfoalkylating agents are believed to be the "dimeric esters" of the hydroxy alkane sulfonic acids.
不含磺酮的磺基烷基化剂可以通过将丙烷或丁烷的羟基烷磺酸或相应的含有5或6个环成员的磺酮与高达四倍摩尔量的水加热到80℃至180℃的温度区域来获得。这些磺基烷基化剂被认为是羟基烷磺酸的“二聚酯”。
