摘　　要：以α-异佛尔酮为原料,催化异构化制备β-异佛尔酮。研究了精馏柱类型、塔顶温度、催化剂、催化剂用量及回流比对产品纯度的影响。在1.5 m不锈钢θ环填充柱,回流比为20,塔顶温度为120℃条件下,β-异佛尔酮纯度为96.5%。β-isophorone was synthesized via catalytic isomerization ofα-isophorone. Effects of rectifying tower type, tower top temperature, catalyst type and catalyst amount on the purity of product were studied. The results show that, under the conditions of 1.5 m packed column, reflux ratio of 20, tower top temperature of 120 oC, the purity of achievedβ-isophorone can reach to 96.5%.
