AbstractS‐Alkylthiocarboxylic acids and their potassium salts were prepared by photoaddition of α‐olefins (C10, C12, and C14) with mercapto carboxylic acids such as thiomalic acid, thiopropionic acid, and thioglycolic acid. The physicochemical solution properties and thermal stabilities for three series of thiosurfactants were evaluated. S‐Alkylthiocarboxylic acids that contain bridged S‐bonds provide excellent thermally stable surfactants, and their alkaline salts exhibit good surface activity.
摘要通过α-烯烃(C10、C12 和 C14)与巯基羧酸(如硫代马来酸、硫代丙酸和硫代乙醇酸)的光加成,制备了烷基硫代羧酸及其钾盐。对三个系列的硫代表面活性剂的溶液理化性质和热稳定性进行了评估。含有桥接 S 键的 S-烷基硫代羧酸是热稳定性极佳的表面活性剂,其碱性盐具有良好的表面活性。
