摘要
2(4异丁基苯基)丙酸(俗称布洛芬)是一种重要的解热镇痛消炎药物[1],经典的生产路线是由异丁基苯出发,经弗克反应、达村缩合,最后经氧化制得[2];其合成步骤多,成品精制难,生产成本高.美国于1992年通过1(4异丁基苯基)乙醇(IBPE)羰...
In this paper, the effects of NaOH amount, reaction temperature, catalyst concentration and hydrogen pressure on the hydrogenation of pisobutyl acetophenone (IBAP) over 5% Pd/C are investigated in detail. The optimum reaction conditions are as follows: p (H2) =09 MPa, T=303 K, m (5%Pd/C) =04 g, and m (NaOH) =008 g. The conversion of IBAP and the yield of 1(4isobutylphenyl)ethanol (IBPE) are 995% and 958%, respectively. The hydrogenation reaction follows the first order kinetics with respect to IBAP concentration, catalyst concentration and hydrogen pressure, respectively. The activation energy for this reaction is ca 422 kJ/mol.
