Modified MCM-41 as Catalyst for Synthesis of Geranyl Propionate
摘要
Abstract
SO42–/mobile crystalline material（MCM-41） was prepared via the modification of MCM-41 with H2SO4.Its structure was characterized by X-ray diffraction（XRD）,Fourier transform infrared spectroscopy（FTIR）,NH3-temperature programmed desorption（NH3-TPD） and N2 adsorption-desorption,respectively.The geranyl propionate（GP） was synthesized.Using SO42–/MCM-41 as a catalyst.The effects of amount and regeneration of the catalyst on the reaction results were investigated.H2SO4,MCM-41 and SO42–/MCM-41 were used as a catalyst for the synthesis of GP,respectively,and their catalytic properties were compared.The results show that the mesoporous molecular sieves SO42–/MCM-41with a long-range order and a good crystallinity can be obtained by dipping the mesoporous molecular sieves MCM-41 with H2SO4 of 0.50 mol/L for 1.0 h and calcining at 450 ℃ for 3.0 h.The conversion could be 88.82% and the selectivity of GP was 85.20% when the modified MCM-41 was used as a catalyst for the esterification of geraniol.The modification effect with H2SO4 on the structure of MCM-41 mesoporous molecular sieves was not obvious,but could improve its acidity.关键词
