Abstract
Nitrobenzene was synthesized from benzene and nitric acid using solid super acid ZrO2/SO42- as catalyst.The optimized reaction conditions are as follows: the activation temperature of catalyst is650℃,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%.
