3,3-双(氯甲基)氧杂环丁烷的制备

The Preparation of 3,3Bis(chloromethyl)oxetane (BCMO)

以季戊四醇为原料，氯化亚砜为氯化剂，通过Ｖｉｌｓｍｅｉｅｒ试剂及控制它们的摩尔投料比和加料顺序，采用碱性氧化铝柱分离，一步制备出了可直接用于阳离子开环聚合的３，３-双（氯甲基）氧杂环丁烷（ＢＣＭＯ），收率为７８.９％。

The title compound is prepared from pentaerythritol,using Vilsmeier reagent.By controlling feed ratio and feed sequence,its purity is so high that it can be polymerised directly.The yield of the product is ≥78%.
