超声辐射选择性还原β-紫罗兰酮工艺
Selective reduction of β-ionone during ultrasounic irridiation
摘要
Abstract
The procedure of selective reduction of β-ionone by ammoniumformate as hydrogen donor and mass fraction 10％ of Pd/C as catalyst was studied using anhydrous ethylol as solvent during the ultrasonic irridiation. The effect of ultrasonic power, reaction temperature, reaction time, the quantity of 10％ Pd/C and ammoniumformate were investigated,and the reaction conditions were optimized, and the products were characterized by IR, 1H-NMR, 13C-NMR, MS and elemental analysis The results show that conversion of β-iunone 100％ and dihydro-β-ionone is the major product in yield of 94.8％ along with dihydro-β-ionol under the conditions as follows: m(β-ionone): m(10％ Pd/C) is 100:5,n(β-ionone): n(HCOONH4) is 1:3, ultrasonic power 150 W and anhydrous ethylol 50 mL at 50 ℃ for 8 min at ambient pressure. The Pd/C catalyst is easy for recovery and can be reused again over 6 times.关键词
