纳米固体超强酸SO4(上标 2-)/Fe2O3催化合成没食子酸正丁酯的研究
摘要
Nanometer solid super-acid SO4(superscript 2-)/Fe2O3 are prepared by FeCl3 and determined by the TEM. The spectrum of the TEM indicated: it is approximately 100nm. Effects of baking temperature and baking time in nanometer solid super-acid preparation are studied. The butyl gallate is synthesized by butyl alcohol and gallic acid by nanometer solid super-acid SO4(superscript 2-)/Fe2O3. The influencing factors of the reaction are investigated. The optimal reaction conditions are as follows: the molar ratio of alcohol to gallic acid is 6:1, the quantity of catalyst is 3%, reaction time is 2h, and the yield of butyl gallate is 64.9%.
