    Abstract: Trifluoromethylsulfonic acid has been found to be an extremely useful catalyst for the manufacture of mercaptans from olefins or viscous polyolefins and hydrogen sulfide. Also a novel process for the preparation of mercaptans is disclosed which proven comprises reacting olefins or polyolefins at a temperature of about -10.degree. to 70.degree. C. with hydrogen sulfide under pressure of about 1 to 10 atmospheres in the presence of about 0.05 to 10 percent by weight of the olefins of the trifluoromethylsulfonic acid. The mercaptans produced according to the novel process are useful in the preparation of nonionic surfactants for lubricating oils and in the enhanced oil recovery as well as for biocides. Novel beta-polybutenylsulfoxy-alpha-hydroxyethylbenzenes have also been prepared. These are useful in the preparation of nonionic surfactants for lubricating oils and as biocides.
