摘要
研究了水溶性钌-氢配合物RuHCl(TPPTS)3在水/有机两相体系中催化1-己烯双键异构化反应.考察了反应温度、时间、膦配体浓度、相转移催化剂CTAB浓度以及底物与催化剂摩尔比等对转化率和产物选择性的影响.在最佳条件下1-己烯转化率达到82.4%,2-己烯选择性21.2%,3-己烯61.2%,没有发现骨架异构化.催化剂可重复使用5次.
The double bond isomerization reaction of 1-hexene catalyzed by RuHCl(TPPTS)3 was studied .The effects of reaction temperature, concentrations of CTAB, TPPTS, molar ratio of 1-hexene to RuHCl(TPPTS)3 on the conversion and selectivity of 2-hexene and 3-hexene were investigated. The conversion of 1-hexene attained 82.4% and the selectivity of 2-hexene and 3-hexene were 21.2% and 61.2% respectively under optimum conditions without skeletal isomerization. The catalyst could use for 5 time repeatedly.
