煤基固体酸催化合成席夫碱反应
Synthesis of Schiff Base Catalyzed by Coal-based Solid Acid Catalyst
摘要
Abstract
A coal-based solid acid catalyst AC@PANI-SO3H(APS) was prepared in situ by solution polymerization using coal-based activated carbon(AC) and aniline(ANI) as raw materials.The catalyst was characterized by scanning elecrton microscopy(SEM), Fourier transform infrared spectrometer(FTIR), X-ray photoelectron spectroscopy(XPS), and thermal gravimetric analyzer(TGA).Its catalytic activity on yield of Schiff bases was studied under microwave irradiation.The results show that with 5 %(based on the amount of o-phenylenediamine per mole) catalyst, the reaction in ethanol is performed for 3 to 20 min, the yield of Schiff-bases is 80% to 93%.It is proved that the catalyst exhibits good catalytic activity in the microwave-catalyzed synthesis of Schiff base.The reaction time is short, the process is simple to operate, and the catalyst can be reused 5 times.The main reason for the decrease of the activity of the catalyst after repeated 5 times is that the sulfonic acid functional groups bonded to the solid acid surface is disappeared and the activity is decreased.关键词
