    • The invention relates to a method for producing enol ethers of formula (I), by reacting alcohols of formula (II): R OH and/or acetals or ketals of formula (III), in which R is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic rest, which can carry other substituents which do not react with acetylenes or allenes, and the rests R independently of each other represent hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic rests which can be joined such that they form a ring, and where m is 0 or 1, with acetylenes or allenes of formulas (IV) or (V) in the gaseous phase at elevated temperature in the presence of a heterogeneous catalyst containing zinc or cadmium together with silicon and oxygen, and by isolating the enol ethers of formula (I) by distillation.
    • 一种制备式(I)的烯醇醚,其中由式(II)的醇的反应过程,R <1> OH,和/或,式缩醛或缩酮(III),其中R <1>是脂族, 脂环族,芳脂族,芳族或杂环基团,其中这些基团可带有进一步的取代基不与乙炔或丙二烯反应,所述基团彼此独立地R 2是氢或脂族,脂环族,芳脂族,是芳族或杂环基团,其下 形成一个环可一起在高温下,在锌或含镉的存在下加入和m是0或1,与式(IV)和(V)的炔或丙二烯,在气相中,有硅和氧的非均相催化剂和沿 通过蒸馏式(I)的烯醇醚的隔离。
