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％。
以α-異彿爾酮為原料，催化異構化製備β-異彿爾酮。研究瞭精餾柱類型、塔頂溫度、催化劑、催化劑用量及迴流比對產品純度的影響。在1.5 m不鏽鋼θ環填充柱，迴流比為20，塔頂溫度為120℃條件下，β-異彿爾酮純度為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%.
