CATALYTIC HYDROGENOLYSIS OF ORGANIC THIOCYANATES AND DISULFIDES TO THIOLS

摘要

A process for the preparation of a thiol comprising reacting hydrogen with a thiocyanate or disulfide wherein the reaction with thiocyanate is conducted in the presence of a catalyst comprising a Group VIII metal or a mixture thereof; and the reaction with thiocyanate or with disulfide is conducted in the presence of a catalyst comprising a Group VIII metal or mixture thereof in the presence of a modifier metal selected from a group consisting of Group IB, Group IIB, Group IIIA, Group IVA, Group VA and Group VIA metal or mixture thereof, said catalyst being on a porous insoluble support.
