对硝基苯胺催化加氢合成对苯二胺的绿色工艺
Green Process for Synthesis of p-Phenylenediamine by Catalytic Hydrogenation of p-Nitroaniline
摘要
Abstract
The synthesis of p-phenylenediamine by the hydrogenation of p-nitroaniline on a Rainey nickel catalyst with water as the solvent was studied, which was a green process. The influences of reaction conditions, namely reaction pressure, reaction temperature, stirring speed, p-nitroaniline dosage and catalyst dosage on the catalytic hydrogenation were investigated. The results showed that under the optimum reaction conditions: water dosage 400 mL, p-nitroaniline dosage 175 g, Raney Ni catalyst dosage 5.0 g, stirring speed 1 000 r/min, reaction temperature 50 ℃ and reaction pressure 3.0 MPa, the conversion of p-nitroaniline, the yield and purity of p-nitroaniline could reach 100.0%, 98.9% and 100.0%(w), respectively. Both the solvent and the catalyst could be reused. The process is safe and environmentally friendly with low cost and low energy consumption.关键词
