以桃金娘烯醛为原料，以共沉淀法制备的Cu/ZnO 为新型催化剂，在裂解反应装置中进行催化桃金娘烯醛异构化合成紫苏醛反应。考察了异构化条件对反应转化率和选择性的影响规律。结果表明：在焙烧温度为300℃，反应温度为350℃，进样速度为2．0 mL/min，原料与催化剂的质量比为4∶5的条件下，原料的转化率达88．79％，紫苏醛的选择性可达54．72％。质谱与红外分析结果与紫苏醛的标准谱图相符。

In this paper,synthesis of perillaldehyde from myrtenal by isomerization in the cracking re-actor is carried out by using Cu/ZnO prepared from co-precipitation as the catalyst.The influence of isomerization reaction variables on the conversion and selectivity of the reactions is evaluated.The results show that 88.79%conversion rate of materials and 54.72%selectivity of perillaldehyde are ob-tained when Cu/ZnO is as catalyst for the reaction at 350 ℃ under the conditions that the feeding rate of 2 .0 mL/min,mass ratio of material and catalyst of 4∶5 ,and calcination temperature of 300 ℃. The results of MS and FT-IR almost match the standard mass spectrogram of perillaldehyde.
