Abstract
4-carboxyl-N-Hydroxyphthalimide was synthesized and combined with oxamide cobalt(Ⅱ) complex in the phenylethane oxidation by oxygen molecule.It was suggested that when the reaction temperature was 100℃,the pressure of the oxygen 0.3MPa,and reaction time 10h,the conversion of phenylethane reached 95.7% and the selectivity of hypnone,1-phenyl ethanol and 1-phenyl hydrogen peroxide reached 90.5%,3.2% and 6.6%,respectively.Compared with NHPI/Co(OAc)2 catalytic system,they all improved markedly.Using this catalytic system,the oxidation reactions proceed under mild conditions and give high conversions and selectivity.
