Abstract

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.

Key words: Ti-MWW zeolite, methyl ethyl ketone, ammoximation, methyl ethyl ketone oxime, slurry reactor, hydrogen superoxide
