摘要

以多聚磷酸(PPA)为催化剂

邻苯二胺和对氨基苯甲酸为反应物

在微波辐射下合成2-(4-氨基苯基)苯并咪唑.考察了微波辐射时间、反应物料摩尔比、催化剂用量对反应产率的影响后

通过测熔点、红外光谱和核磁共振谱手段对产品结构进行表征分析.通过对实验数据进行分析

得出反应的最佳条件为:微波辐射功率80W

辐射时间10min

n(邻苯二胺)∶n(对氨基苯甲酸)为1∶1.3

催化剂用量为6mL时

产率可达89.5%.产物熔点为227.4～229.8℃.

Abstract

2-(4-aminophenyl)benzimidazole were synthesized by the reaction of o-phenylenediamine with 4-Aminobenzoic acid in the presence of polyphosphoric acid under microwave irradiation.The effect of the microwave irradiation time

a reaction material mole of ratio

the catalyst quantity to responded the production rate were examined

and the products were analyzed by measuring its melting point

IR and 1HNMR.Through the analysis of experiment data

the optimum conditions are as follows: microwave power of 80 W

microwave irradiation time of 10 min

the mole ratio of o-phenylenediamine to 4-Aminobenzoic acid of 1∶1.3

catalyst quantity of 6 mL

the yield is 89.5%

and the melting point is 227.4 ℃ to 229.8 ℃.
