摘要: 系统研究了 TS-1/H2O2 催化二乙胺 (DEA) 氧化制备二乙基羟胺 (DEHA) 的反应规律, 考察了 DEA 氧化及 DEHA 氧化反应之间的竞争关系. 结果表明, H2O2 以连续方式进料时, DEA 转化率及 H2O2 有效利用率明显提高, 而反应体系中 DEA/H2O2 的摩尔比对 DEHA 选择性的影响较大. TS-1 既可催化 DEA 的氧化, 又可催化产物 DEHA 的进一步氧化.

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.
