使用高磺化度的磺化聚醚砜为固体酸催化剂合成了乙酸甘油酯。考察反应物投料比、反应温度、催化剂用量等对甘油转化率和乙酸甘油酯选择性的影响。研究发现,与磺化聚苯乙烯催化剂相比,高磺化度的磺化聚醚砜催化剂具有更高的甘油转化率和二、三乙酸甘油酯选择性。并且催化剂可以重复使用多次,催化效率没有明显降低。 Glycerol acetate was synthesized using sulfonated polyethersulfone with high degree of sulfonation as solid acid catalyst. Effects of reactant feed ratio, reaction temperature, amount of catalyst on glycerol conversion and glycerol acetate selectivity were investigated. The study found that, compared with the sulfonated polystyrene catalyst, the sulfonated polyether sulfone catalyst with higher degree of sulfonation has higher glycerol conversion and di-, triacetin selectivity. And the catalyst can be reused many times, the catalytic efficiency is not significantly reduced.
