The industrial production of N-(2 - benzimidazole -yl) carbamate ( carbendazim) multi -product and the cost of the problem , to study the synthesis has important practical significance . The benzimidazolyl -acetate is carbendazim a derivative , may have a particular biological effect , and therefore discussed the synthesis of a benzimidazolyl -acetate . The thesis under normal temperature and pressure from the raw methyl chloroformate was synthesized by Cyanamid , acidification, rings carbendazim . Discusses a phase transfer catalyst , the alkali catalyst and other reaction conditions on the synthesis of carbendazim methods , and synthesized benzimidazolyl -acetate intermediate cyanamide acetate. Synthesis process , the target compounds DSC, UV , IR and ~ 1H-NMR spectrum analysis and identification .
