摘要
以硝酸为硝化剂,自制沸石固体酸为催化剂,进行了硝基苯合成新工艺的研究,优化的反应条件为:常压80~100℃、反应时间3h,硝酸/苯(体积比)1.5~3.5时,硝基苯收率>96%。
The catalytic synthesis of nitrobenzene using nitric acid as a nitrating agent and solid acid as a catalyst was studied . The results showed that metals modified MFI structure zeolite M2+1 MFI shown good activity and high selectivity . The optimized reaction condition temperature: 80100 ,reaction time 3 hr , nitric acid/benzene volume ratio 1.53.5 .
