  公开（公告）日：1996-03-20

  A process for producing an unsaturated ether comprises subjecting a glycol ether to intramolecular dehydration in the gas phase in the presence of a catalyst to convert the glycol ether into an unsaturated ether directly in a one-step reaction. As the catalyst, an oxide containing, for example, silicon and an alkali metal is used. The process, which uses no auxiliary raw material, can produce an unsaturated ether (a vinyl ether and/or an allyl ether) simply and safely without generating any waste material derived from the auxiliary raw material.

  一种生产不饱和醚的工艺包括在催化剂存在下，使乙二醇醚在气相中进行分子内脱水，从而在一步反应中直接将乙二醇醚转化为不饱和醚。催化剂是一种含有硅和碱金属的氧化物。该工艺不使用辅助原料，可以简单安全地生产出不饱和醚（乙烯基醚和/或烯丙基醚），而不会产生任何来自辅助原料的废料。
