| Abstract: | Catechol was used as the starting material to give 3,4-methylenedioxy-nitrobenzene which was synthesized by the process of methylenation and nitration.The optimum temperature of the methylenation was 120 ℃.The optimum conditions of nitration were:the molar ratio of 1,2-(methylenedioxy)benzene to nutrate was 1∶1.3,concentration of HNO3 was 50%.The total yield and the purity of the product were 90.7% and 99.9%. |
