Abstract

In the preparation process of oxime over the titanosilicate/H₂O₂ system, the reaction performance of oxime influenced the efficiency and stability of the process directly. The reaction behavior of methyl ethyl ketone oxime produced from ammoximation of methyl ethyl ketone catalyzed by the Ti-MWW/H₂O₂ system was studied. The Ti-MWW and H₂O₂ together resulted in the hydrolysis of methyl ethyl ketone oxime to methyl ethyl ketone, NO_x, etc. Thus, the system was from alkalescence to acidity. The same phenomena also existed in the TS-1/H₂O₂ system for cyclohexanone oxime production. This experimental result was beneficial for the increase of the efficiency and the stability of the process over the titanosilicate/H₂O₂ system.
