Process for producing heterocyclic aldehydes.

摘要

A process for producing a heterocyclic aldehyde is disclosed, comprising hydrogenating a heterocyclic carboxylic acid containing at least one atom selected from nitrogen, sulfur, and oxygen atoms or a derivative thereof with molecular hydrogen in the presence of a catalyst containing an oxide of at least one element selected from the group consisting of zinc, yttriun, lanthanides, and the elements of the group 4A of the Periodic Table. The process attains high conversions, high selectivities, and high yields.
