PRODUCTION OF 2-MERCAPTOBENZIMIDAZOLE BY REACTING O-PHENYLENE DIAMINE AND CARBON DISULFIDE

摘要

Process for the production of highly pure 2-mercaptobenzimidazole, in high yield, from o-phenylenediamine and carbon sulfide, characterized in that the reaction is carried out in a solvent that contains all the reaction components homogeneously dissolved, The 2-mercaptobenzimidazole formed is extracted with a dilute aqueous solution of alkali hydroxide and precipitated from this by acidification.
