苯甲醛正丁硫醇缩醛的合成研究

The Synthesis of Benzaldehyde Butyl Mercaptal

０４９ｍｏｌ苯甲醛和１３ｍｌ正丁硫醇在６ｍｍｏｌ对甲苯磺酸催化下发生反应，合成了相应的缩硫醛，产率８２８％。经红外光谱、元素分析、核磁共振检测对产物结构进行了确证。

Benzaldehyde(0.049mol)was treated with butylthiol(13ml)in cyclohexane in the presence of ptoluenesulfonic acid(6mmol)to give 82.8% benzaldehyde butyl mercaptal.The synthesis of this thioacetal was reported in this paper.And the structure of this material was proved by way of IR spectrum, 1HNMR spectrum datum.
