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.
