由山苍子油合成假性紫罗兰酮和紫罗兰酮的研究

Studies on Synthesizing the Pseudoionone and Ionone from Litea cubeba Oil

采用正交试验设计法，探讨了以山苍子油为原料，在微波辐射下，合成假性紫罗兰酮和紫罗兰酮的条件；筛选了获得假性紫罗酮和紫罗兰酮较高产率的复合催化剂。试验结果表明，采用微波促进催化合成技术，可以使柠檬醛与丙酮的醇醛缩合反应的时间缩短４～８ｈ，产率提高１２％以上。

By orthogonal design, the conditions for the synthesis of pseudoionone and ionone from Litea cubeba oil under microwave irradiation were explored. A better catalysis was selected. The experimental results showed that using microwave irradiation reduced the reacting time of the condensation citral and acetone about 4～8 hours, and increased the yield by over 12%. All there compounds were indentified by IR and GC etc.
