  Unsymmetrical ethers are obtained in excellent yields by the catalytic etherification of alcohols with ketones or aldehydes in the presence of Pd/C under an atmospheric pressure of hydrogen when water produced by the reaction is continuously removed by bubbling hydrogen through the reaction mixture.

  当反应产生的水通过反应混合物中的氢气鼓泡连续除去时，在 Pd/C 存在下，在氢气压力下，通过醇与酮或醛的催化醚化反应，以极好的收率获得不对称醚。

  Ether compounds, which are useful as solvents, cosmetics, detergents, lubricants, emulsifiers and so on, are produced by reacting (a) a hydroxy compound with a carbonyl compound or (b) a carbonyl compound under hydrogen atmosphere in the presence of a catalyst with ease and at a low cost. The reaction is carried out while removing out produced water by using a dehydrating agent during the reaction; by distilling off the water by azeotropic dehydration and the like; or by blowing gases such as hydrogen gas to flow through the reaction system.

  醚类化合物可用作溶剂、化妆品、洗涤剂、润滑剂、乳化剂等，其生产工艺为：(a)羟基化合物与羰基化合物反应，或(b)羰基化合物在氢气环境下与催化剂反应，反应简便，成本低廉。在反应过程中使用脱水剂，通过共沸脱水等方法蒸馏出水，或吹入氢气等气体流经反应系统，在除去生成水的同时进行反应。
