摘　　要：本文报导使用国产强碱201×7(711-OH)型阴离子交换树脂作催化剂,在氮气中和56℃下催化柠檬醛与丙酮缩合合成假紫罗兰酮,产率为80.17％,纯度97.5％。研究了温度、溶剂及柠檬醛、丙酮不同用量对缩合反应的影响。This paper describes the synthesis of pseudoinone (I) by condensation of citral with acetone using a basic anion exchanger 711 -OH as catalyst in a nitrogen stream at 56℃ to give a yield of 80.2% I ,purity 97.5%. The effect of temperature solvents, and the amount of citral and acetone was investigated.
