摘　　要：在液相连续於浆床反应器中,Ti-MWW/H2O2体系表现出较高的催化丁酮氨肟化制备丁酮肟的活性,详细考察了各反应条件对Ti-MWW分子筛催化性能的影响.结果表明,在优化的反应条件下,丁酮转化率和丁酮肟选择性分别达95%和99%以上;均优于传统的钛硅分子筛TS-1,且稳定性也更高.The catalytic performance of Ti-MWW/H2O2 system for the ammoximation of methyl ethyl ketone（MEK） to methyl ethyl ke-tone oxime（MEKO） was investigated in a continuous slurry reactor.The effects of various reaction parameters on the catalytic performance of Ti-MWW were studied in detail.Under the optimized reaction conditions,Ti-MWW showed MEK conversion and MEKO selectivity over 95% and 99%,respectively.Moreover,Ti-MWW can serve as an extremely robust catalyst,exhibiting a longer lifetime in comparison with conventional TS-1.
