摘要 文章以3,4-二氨基苯甲酸和乳酸为主要原料,合成了2-羟乙基-苯并咪唑-5-羧酸,并探讨了反应温度、反应物料摩尔比以及反应时间对目标产物的影响。通过红外、熔点、元素分析等方法对产物进行了表征。得到合成2-羟乙基-苯并咪唑-5-羧酸的最佳条件为以4 mol/L HCl溶液作为溶剂,同时作为催化剂,反应温度为130℃,反应时间12 h,3,4-二氨基苯甲酸与乳酸的最佳摩尔比为1∶4,反应条件温和,产物收率达到70%。 The 2-hydroxyethyl-benzimidazole-5-carboxylic acid was prepared by using 3,4 - diamino-benzoic acid and lactic acid as main materials. The product was characterized by FT-IR, melting point, elemental analysis, its reaction conditions were researched, the results showed that optimal reaction conditions: 4 mol/L HCI as solution and catalyst, the reaction temperature was 130 ℃, the reaction time 12 h, 3,4 - diamino-benzoic acid and lactic acid of the best molar ratio of 1 : 4, the yield can reach 70 %.
