ABSTRACT:
Disclosed is a method of making a mercaptan by reacting hydrogen sulfide with an olefin in the presence of a heterogeneous acidic catalyst. The catalyst can be made by calcining a mixture of a hydroxide, such as Zr(OH).sub.4 or Ti(OH).sub.4, with an acidic site donor, such as H.sub.2 SO.sub.4, (NH.sub.4).sub.2 SO.sub.4, or WO.sub.3.
