摘　　要：The catalytic behaviours of Ruthenium comlex RhC12(TPPTS) 3 as catalyst precursor for the selective hydrogenation of Carbon-crbon double bond in methylvinylketone were studied in biphasic system (aqueous/ cyclohexane ). When the hydrogenation was carried out under the following condition: [Ru] = 2 × 10-3mol/L [TPPTS]/[Ru]=3, 2. 0MPa, H2O: 10mL, cyclohexane: 5mL, subettate: 25mmol,stiring speed: 600r/min, the conversion reached 70.13 % and the selectivity for the hydrosenation of C=C was 100%. The effect of molar raio of TPPTS to Ru on the activity was remarkable. When [TPPTS]/[Ru] increased to 15, the conversion raised to 100% and the selectivit was kept unchanged.The catalytic behaviours of Ruthenium comlex RhC12(TPPTS) 3 as catalyst precursor for the selective hydrogenation of Carbon-crbon double bond in methylvinylketone were studied in biphasic system (aqueous/ cyclohexane ).
