摘要：
Alkyl alkoxy, aryl alkoxy or alkylaryl alkoxy halides are prepared by reacting the corresponding alkoxy alcohol with a halogenating agent, eg, thionyl chloride, in the presence of a soluble metal or compound of a metal of Groups IA or IIA of the Periodic Table 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.
