ABSTRACT:
A method is provided for preparing mercaptans by catalytic cleavage of organic sulfides with hydrogen sulfide in the presence of a supported phosphotungstic acid catalyst. The process is particularly advantageous with n-alkyl sulfide feedstock and being highly selective for producing n-alkyl mercaptan product. In one embodiment the presence of carbon disulfide in the reaction mixture increases the conversion at low temperature as compared to the process without the presence of carbon disulfide.
