异黄樟油素液相氧化合成洋茉莉醛的研究

2Synthesis of Heliotropin through Liquid-Phase Oxidation of Isosafrole

通过不同条件下的实验，得出由异黄樟油素液相氧化合成洋茉莉醛的适宜工艺条件．＿当异黄樟油素与高锰酸钾的重量比为１∶１时，向混合液中滴加酸，并通入氧气，在７０℃下反应２．５ｈ，醛得率为４３．３％．

By the comparison of experiment results in different conditions, the optimum technical condition that synthesis of heliotropin through liquid-phase oxidation of isosafrole has been found. Under the term of the weight ratio of lsosafrole and KMO 4 is 1∶1, acid and oxygen is added to the mixture, through chemical reaction of 2.5 hours at 70℃ and the rate of heliotropin reaches 43.3%.
