ABSTRACT:
Thiol alkoxylates having utility, for instance, an nonionic surfactants in detergent formulations are prepared by the reaction of alkane thiols with alkylene oxides in the presence of a catalytically effective amount of one or more basic alkoxylation catalysts and additionally in the presence of as a reaction promoter added thiol alkoxylate having in the alkoxylate molecule from one to about 30 adducts of one or more alkylene oxides. The presence of the added thiol alkoxylate promoter improves the handling of the reaction mixture and facilitates the production of thiol alkoxylates having low content of polyalkylene glycol byproduct.
