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.

Abstract: The catalytic performance of Ti-MWW/H2O2 system for the ammoximation of methyl ethyl ketone (MEK) to methyl ethyl ketone 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.
