摘要
综述了结晶硫酸铁,浓硫酸(微波辐照),SO_4^(2-)/TiO_2-Al_2O_3,TiSiW_(12)O_(40)/TiO_2,SO_4^(2-)/膨润土,磷钨、硅钨杂多酸等7种催化剂分别催化合成尼泊金丁酯的实验结果。结果表明,SO_4^(2-)/TiO_2-Al_2O_3和TiSiW_(12)O_(40)/TiO_2两种催化剂对合成尼泊金丁酯的酯收率较高,有实际应用价值。
The research on catalytic synthesis of butyl p - hydroxybenzoate respectively using Fe2(SO4)3 · xH2O, H2SO4(Microwave Irradiation) , SO42-/TiO2 - Al2O3 , TiSiW12O40/TiO2, SO42-/bentonite, phosphotungstic acid, and silicotungstic acid as catalysts are reviewed. The results show that SO42-/TiO2 - Al2O3 and TiSiW12O40/TiO2 are excellent catalysts for synthesis of butyl p - hydroxybenzoate with higher yields and practical application value.
