    • The present invention provides for a simplified process for converting ethers into their corresponding alcohols comprising forming an aqueous mixture of the ether and at least about 50% by weight water and heating the mixture under autogeneous pressure at a temperature of from about 250.degree. to 450.degree. C., more preferably from about 250.degree. C. up to the critical temperature of water which is about 374.degree. C. Heating is continued for a period of time sufficient to convert at least about 20% by weight of the ether, usually from about 5 up to about 120 minutes, depending on temperature and the amount of water present, and the identity of the starting ether feedstock.The process may be characterized as an aquathermolysis reaction wherein the reaction proceeds in water primarily through ionic routes rather than through free radical routes. Accordingly, relatively high conversion rates and good yields of alcohol and other reaction by-products may be obtained without the necessity of using a catalyst in the process.
    • 本发明提供了将醚转化成其相应的醇的简化方法,包括形成醚的水性混合物和至少约50重量%的水,并在约250-450℃的温度下在自主压力下加热混合物 更优选约250℃至约374℃的水的临界温度。继续加热足够的时间以使至少约20重量%的乙醚转化成通常为约 5至约120分钟,这取决于温度和存在的水的量以及起始醚原料的特性。 该方法可以表征为水解溶解反应,其中反应在水中主要通过离子路线而不是通过自由基途径进行。 因此,可以获得醇和其它反应副产物的相对高的转化率和良好的产率,而不需要在该方法中使用催化剂。
