Quaternary sulfoalkyl or sulfoalkenyl salts of tertiary amine bases are prepared by reacting the tertiary amine bases at elevated temperatures with a hydroxy alkane sulfonic acid or a hydroxyalkene sulphonic acid.
三级胺碱与羟基烷磺酸或羟基烯烷磺酸在高温下反应,制备出季铵磺基烷基或烯基盐。

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.
