Abstract
Interchange reactions between organosulfides and mercaptans are promoted by the use of catalysts containing tungsten and molybdenum oxide.
Claims17
A process for the reaction of organosulfides with mercaptans which comprises:
- contacting a feed consisting essentially of organosulfide and mercaptan in the presence of a catalyst which contains a reaction product of a Group III A component and a phospho Group VIB reactant under reaction conditions to exchange one organic moiety of the organosulfide with the hydrogen of the mercaptan.
A process for the reaction of organosulfides with mercaptans which comprises:
- contacting an organosulfide with a mercaptan in the presence of a catalyst which contains a reaction product of a Group IIIA component and a phospho molybdic reactant under reaction conditions to exchange one organic moiety of the organosulfide with the hydrogen of the mercaptan.
A process for the reaction of organosulfides with mercaptans which comprises:
- contacting an organosulfide with a mercaptan in the presence of a phospho Group VIB reactant on a support selected from the group consisting of metal aluminate and Group IIIA phosphate, under reaction conditions to exchange one organic moiety of the organosulfide with the hydrogen of the mercaptan.
A process for the reaction of organosulfides with mercaptans which comprises:
- contacting di-n-propylsulfide with thiophenol in the presence of a catalyst which contains a reaction product of a Group IIIA component and a phospho Group VIB reactant under reaction conditions to exchange one organic moiety of the organosulfide with the hydrogen of the mercaptan.
