常压条件下Pd/C催化邻氯硝基苯加氢反应
Hydrogenation performance ofo-chloronitrobenzene over Pd/C under atmospheric pressure
摘要
Abstract
Activated carbon supported noble metal Pd,Pt and Ru catalysts were prepared by chemical reduction method,and were used in the synthesis ofo-chloroaniline fromo-chloronitrobenzene without any dechlorinating inhibitor and promoter added. The results of the experiments demonstrated that the Pd/C catalysts had better catalytic performances than Pt/C catalysts and Ru/C catalysts. The effects of solvent,reaction temperature,reaction time and other factors were examined using a Pd/C catalyst. The results showed that a 100% conversion ofo-chloronitrobenzene was achieved with a selectivity of 87.4% too-chloroaniline by small amount of 5% Pd/C catalyst under atmospheric pressure. Furthermore,the catalyst could be reused for 6 runs without significant loss of catalytic activity. The new technology was featured as lower reaction pressure,lower catalyst dosage,shorter reaction time and lower dechlorinating,and therefore suitable for industrial production.关键词
