摘要
研究了在超声辐射条件下,采用大孔强碱树脂催化柠檬醛与丙酮缩合制备假性紫罗兰酮的较佳条件,在反应温度为35℃,柠檬醛与丙酮的用量比为1:7(mol/mol),柠檬醛与催化剂的用量比为1∶2(w/w)时,超声反应2h,产率可达95.77%.
The optimum conditions of the pseudo ionone preparation from the condensation of central with acetone catalyzed by macrospore anion exchangers was investigated under ultrasonic irradiation. As the temperature is 35℃, the cenral-to- acetone ratio is 1:7 (mol/mol), the ratio of central to the catalyst is 1:2 (w/w), the ultrasonic reaction lasts 2h, the yield can reach up to 95.77%.
