The degree of hydrogenation of methyl benzoate might be controled by adding the promoters and changing the nano-size of ZnO. For hydrogenation of methyl benzoate to benzaldehyde, the active-structure of a catalyst should be modified to decrease the absorption of benzaldehyde on the surface of it, because benzaldehyde absorbed is hydrogenated easily. Using 30-40%ZnO/γ-Al〓O〓 or Li-30%ZnO/γ-Al〓O〓, a higher selectivity to benzaldehyde is obtained. Hydrogenolysis of methyl benzoate to toluene or benzene is carried out effectively using a catalyst modified. For instance, 45.3% selectivity to benzene and 100% conversion of methyl benzoate at 420℃ was obtained over 10%ZnO/MCM-41 with the nano-size particles of ZnO (2.4nm).
也可以通过助催化剂的添加和活性组分的纳米化,并根据苯甲酸甲酯多步加氢反应的特点实行加氢深度的调控:苯甲酸甲酯选择性加氢制苯甲醛中,由于苯甲醛容易进一步加氢,需要对活性结构进行调变,以减弱苯甲醛的吸附,使用30-40%ZnO/γ-Al〓O〓催化剂或Li调变的Li-30%ZnO/γ-Al〓O〓催化剂,可获得较高的苯甲酸甲酯加氢制苯甲醛的活性;采用同样的方式,苯甲酸甲酯选择性氢解为甲苯或苯也获得了较好的结果,如使用ZnO纳米化的10%ZnO/MCM-41催化剂,在420℃,可获得45.3%的苯选择性,苯甲酸甲酯完全转化。
