Preparation of alkoxy halides. |
摘要 |
<p>Alkyl-, aryl- or alkylaryl-alkoxy halides are prepared by reacting the corresponding alcohol, phenol or alkyl phenol with ethylene oxide and/or propylene oxide in the presence of an amine catalyst to form an alkoxy alcohol, and directly reacting the latter with a halogenating agent in the continuing presence of the amine catalyst.</p><p>Neutralisation of the product and/or catalyst removal from the first stage is no longer necessary and reaction rates and yields are increased in the second stage.</p> |
