The present invention refers to a process for the preparation of unsaturated ketones or aldehydes by pyrolysis of a lactone, in the presence of a reducing agent such as molecular hydrogen or a carboxylic acid, and in the presence of a catalyst, optionally supported, comprising at least one metal selected from the group consisting of Y, Ti, Cd, Mn, Zn, Sc and Zr.
本发明涉及一种制备不饱和酮或醛的过程,通过在还原剂(如分子氢或
羧酸)存在下,在催化剂的存在下(可选支撑),在至少选择自Y、Ti、Cd、Mn、Zn、Sc和Zr组成的
金属中选择的情况下,通过对内酯进行热解实现。
