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.
本发明涉及一种通过在还原剂(如分子氢或羧酸)存在下,在至少包括Y、Ti、Cd、Mn、Zn、Sc和Zr中选出的至少一种金属组成的催化剂的存在下,通过对内酯进行热解的方法来制备不饱和酮或醛的过程。可选地,所述催化剂可以是支撑型的。
