Imm obil zation of N-(3-Sulfopropyl) pyridinium methanesulfonate ionic liquid and its catalytic pe rformancei n the synthesis of polyoxym ethylene dimethyl ethers
摘要
Abstract
N-(3-Sulfopropyl) pyridinium methanesulfonate ionic liquid was immobilized on HZSM-5 molecular sieves by chemical method and used as the catalyst in the synthesis of polyoxymethylene dimethyl ethers (PODEn).X-ray diffraction, infrared spectroscopy and N2 sorption results showed that the ionic liquid is well immobilized on the molecular sieves.The optimizde rae ctino conditions for the synthesis of PODEnd its ributions are obtained, i.e.m(oi nic liquid)/m(HZSM-5) =0.25, n(CH3OH)n/((CH2O)3) =1.5, 2.2%catla yst, 110℃and 3 h.Under these conid tions, the yield of PODE3~8 , as the ideal additivesf or diesel fuel, reaches 67 .35%, which is much higher than thoes with single ionic liquid or moleculra sieve as the catalyst.The immobilized ionic liquid can be easily recycled na d reusde ; they ield of PODE3~8 remains up to45 .62% after reused for three times.关键词
