摘要
Abstract
Catalytic activities of supported phospho-tungstic acid catalysts in the vapor phase nitration of benzene were studied. The effects on nitration of supports，reaction temperatures，loading amount of hetero-polyacid and molar ratio of benzene to HNO3 were also investigated. The results show that H3PW12O40/SiO2 is an excellent catalyst for the vapor phase nitration of benzene， and the optimum reaction conditions are： molar ratio of benzene to HNO3，2∶1 and reaction temperature， 155～160 ℃. Under above conditions， the yield of nitrobenzene based on HNO3 is 90.6%.关键词
