香料物质苯乙醛及其缩醛合成的新途径

A NEW PROCESS OF MAKING PERFUMES PHENYLACETALDEHYDE AND ITS ACETAL

在强碱性双相催化体系（ＫＯＨ－ＤＭＳＯ）中，被活化的甲醇很容易与苯乙炔发生烯基化反应，生成甲基苯乙烯基醚，其可直接水解制备苯乙醛，也可以直接与醇类作用获得相应的缩醛。

The activated methyl alcohol in super-basic biphase catalytic system(KOH-DMSO )reacts on ethynylbenzene easily,and methyl-styryl ether is produced. Using the methyl-styryl ether gained,we can make phenylacetaldehyde directly by hydrolization,or we can get corresponding acetal directly by it’s reaction on alcohol.Phenylacetaldehyde and its acetal are perfume materials generally used.
