摘要
合成了新型的复合无机固体超强酸 SO_4^(2-)/TiO_2-ZrO_2,把它作为催化剂用于马来酸双酯的合成,其反应速度快,工艺简单,与催化剂硫酸相比,副反应少,对设备腐蚀小。此催化剂不怕水,再生容易,可反复使用。用气相色谱、红外光谱、核磁共振对酯化产物进行了分析鉴定。对催化剂的表面性质进行了考查,并与催化酯化的活性、选择性进行了关联,其结果显示了很好的一致性。
New inorganic compound solid super acids SO_4^(2-)/TiO_2-ZrO_2 were prepared as
catalysts for synthesis of maleates from maleic anhydride and alcohols.Compared
with H_2SO_4 catalyst,it has such advantages as fast reaction rate,simple process,
less by-product and less erosion to epuipment.Being reproduced easily and not
affected by water,the catalyst can be used repeatedly.The products were analyzed
by GC,NMR and IR.The surface property of the catalysts was investigated and
correlated with their activity and selectivity.
