Abstract
Disclosed is a method of making a mercaptan by reacting an aliphatic alcohol with hydrogen sulfide in a continuous gaseous phase reaction. The reaction is performed in the presence of a catalyst which comprises a catalytically active carrier that contains base and/or acid active sites, an alkali metal or alkaline earth metal bicarbonate, carbonate, oxide, or hydroxide, and a transition metal acid or alkali metal or alkaline earth metal salt thereof. Selectivities of close to 100% are obtained.
