Abstract

PURPOSE:To prepare the title compound useful as an antioxidant of rubber and a stabilizer of polymers, in high purity and yield, by a simple process comprising reacting a o-phenylenediamine (derivative) with carbon disulfide in the presence of an alkali hydroxide in an aqueous medium. CONSTITUTION:The objective 2-mercaptobenzimidazole compound is prepared by reacting a o-phenylenediamine (derivative) of the formula (R1-4 are H, halogen, 1-12C alkyl, or alkoxy or nitro, provided that at least one of the R1-4 is not H.) with carbon disulfide in an aqueous medium in the presence of an alkali hydroxide, in the presence or absence of a surface active agent. The amount of the alkali hydroxide is (0.5-2.5)x 1/m mole (m is concentration of the alkali hydroxide) per 1 mole of the compound I. EFFECT:The objective compound can be prepared as free compound in high yield, and usually, a purification process is not necessary.
