Abstract
PURPOSE: An o-phenylene analog dispersed in an aqueous medium is reacted with carbon disulfide to produce high-purity 2-mercaptobenzimidazole analog used as an antioxidant for rubber and heat stabilizer for high polymer in high yield.
CONSTITUTION: An o-phenylene diamine analog of the formula(R1, R2, R3, and R4 are H, halogen, 1W12C alkyl, alkoxy, nitro) is reacted with carbon disulfide to form 2-mercaptobenzimidazole wherein a liquid o-phenylenediamine analog is disperesed into an aqueous medium contaning a base and, when necessary, a surfactant and then the reaction is effected. The product separates form the reaction system as it is formed, thus the yield is very high.
