Synthesis of acetone oxime through acetone ammoximation over TS-1

摘要

The ammoximation of acetone to acetone oxime with 30 wt.% hydrogen peroxide over TS-1 has been studied.The conversion of acetone and the selectivity to acetone oxime can reach 99% and 94%,respectively.The by-products are the corresponding hydrazone,imine and small amounts of unidentified compounds.The influence of various parameters such as solvent,temperature,amounts of catalyst and the NH_3 to acetone molar ratio were investigated.
