研究了溶剂(正己烷、异丙醇(IPA)、四氢呋喃(THF)和甲醇)在Pd/ sio2和Ru/ sio2催化剂上对甲苯加氢反应的影响。采用微量吸附法和红外光谱法对其影响进行了研究。结果表明,正己烷在催化剂上的吸附作用较弱,对甲苯加氢反应的影响较小,而四氢呋喃和甲醇在催化剂上的吸附作用较强,对甲苯加氢反应的抑制作用显著。IPA在催化剂上也有很强的吸附作用,但在催化剂表面表现出氢转移效应,促进了甲苯的转化。
The effects of solvents (n-hexane, isopropanol (IPA), tetrahydrofuran (THF) and methanol) on the hydrogenation of toluene over the Pd/SiO2and Ru/SiO2catalysts were studied. Microcalorimetric adsorption and IR spectroscopy were employed to understand the effects. It was found that n-hexane adsorbed weakly on the catalysts and thus affected less the hydrogenation of toluene, while THF and methanol adsorbed strongly on the catalysts and inhibited the activity of hydrogenation of toluene significantly. IPA also adsorbed strongly on the catalysts, but it exhibited a hydrogen transfer effect on the surfaces that promoted the conversion of toluene.
