Abstract: Oxidation of N,N-diethylamine (DEA) to N,N-diethylhydroxylamine (DEHA) in the catalytic system of TS-1/H2O2 has been studied. The competitive reactions between the oxidation of DEA and DEHA were further investigated. The results suggested that the conversion of DEA and effective utilization of H2O2 can be increased dramatically when H2O2 was added dropwise, while the mole ratio of DEA/H2O2 greatly influenced the selectivity for DEHA. TS-1 can catalyze the oxidation of DEA, as well as the oxidation of DEHA.
