摘要
Abstract
TS-1 molecular sieve was modified with acid, alkali, salt, and used in the ammoxidation reaction of methyl ethyl ketone (MEK). The effects of modified material, reaction temperature, molar ratio of raw materials, mass of catalyst, and reaction time on the reaction, reusability and regeneration of the catalyst were investigated. The result shows that Zn (NO3 )2-modified TS-1 is the optimum catalyst. The optimum reaction conditions are as follows: reaction temperature 70 ℃, n ( NH3 ): n (MEK): n ( H202 ) = 3.5: 1: 2, 12 g TS-1 for 1 mol MEK, reaction time 2.5 h. Under the optimal reaction conditions, the conversion of methyl ethyl ketone (MEK) is up to 97.9％, and the selectivity of methyl ethyl ketoxime (MEKO) is up to 99.6％. The catalyst can be reused three times, and the catalytic properties of TS-1 can be recovered after calcination at 400 ℃.关键词
