PREPARATION OF ALKOXY HALIDES |
| 摘要 |
<p>Alkyl, aryl or alkylaryl alkoxy halides are prepared by reacting the corresponding alkoxy alcohol with a halogenating agent, e.g. thionyl chloride, in the presence of a quaternary ammonium compound as catalyst. In addition to being faster, the catalysed reaction results in an increased yield of desired product and a decrease in the tendency of the polyoxyalkylene chain to cleave.</p> |
