Preparation of 2.2'-dithiobis(benzothiazole) in an aqueous/alcohol reaction medium

摘要

There is disclosed a preparation of (optionally substituted) 2,2'-dithiobis(benzothiazole) by the oxidation of 2-mercaptobenzothiazole using bromate salts as the oxidant in an aqueous/alcohol reaction medium. The process of this invention provides an efficient and practical step in a procedure for the production of 2,2'-dithiobis(benzothiazole) that is virtually pollution free.
