Abstract:
The processes of dimethyl disulfide conversion yielding methanethiol, ethylene and hydrogen sulfide, and the disproportionation of methanethiol formed in this reaction into hydrogen sulfide and dimethyl sulfide proceed on acid-base type catalysts at 350°C in the presence of water. Catalysts with weak proton sites exhibit low activity, which increases with the increasing surface acidity. Catalysts with weak Lewis acid sites and strong basic sites are most active and selective in the reaction of methanethiol formation. The presence of water inhibits the side reaction of disproportionation, thus enhancing the methanethiol formation selectivity.
