摘要
以固体超强酸ZrO2/SO42-为催化剂,苯和硝酸为原料合成硝基苯。最佳反应条件为:催化剂活化温度650℃,苯39.1 g,硝酸与苯摩尔比2.0,催化剂用量1.0 g,反应时间7 h,反应温度75℃,收率达78.3%。
Nitrobenzene was synthesized from benzene and nitric acid using solid super acid ZrO2/SO4^2- as catalyst. The optimized reaction conditions are as follows: the activation temperature of catalyst is 650℃ ,benzene is 39.1 g,n(acid) : n(benzene) is 2.0 ,dosage of catalyst is 1.0 g,reaction time is 7 h, reaction temperature is 75℃,the yield may reached 78.3%.
