Title:
CATALYST FOR CONVERTING MERCAPTANE AND MERCAPTIDE COMPOUND TO DISULFIDE AND CONVERTING METHOD
Document Type and Number:
Japanese Patent JPS5379787
Kind Code:
A
Abstract:
Disclosed is a catalyst and method for converting mercaptans and mercaptide compounds in aqueous alkaline solution to disulfides. Catalytic agent is a metal complex synthesized from 3,3',4,4'-benzophenonetetracarboxylic dianhydride and converted to either the alkali metal salt or to the acid form. The method for oxidizing the mercaptide compounds comprises contacting mercaptans and mercaptide compounds in aqueous alkaline solution with air in the presence of the catalyst and subsequently separating alkaline solution from the resultant disulfide compounds.
