Abstract
A process is disclosed for the preparation of secondary thiols by the addition of H.sub.2 S to C.sub.10 to C.sub.30 linear olefins in the presence of certain zeolite catalysts. The process achieves high selectivity to the secondary thiol and minimizes formation of dialkyl sulfide by-products. The secondary thiol products are of particular advantage for use as intermediates in the preparation of surfactant chemicals.
