A Study of Double Bond Isomerization of 1-Hexene Catalyzed by Water-soluble Ru-H Complex

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.
