摘要：
A process for manufacturing a trimer of a low aliphatic aldehyde having 2-5 carbon atoms and the chlorinated 2-position is disclosed. The process comprises cyclically trimerizing said aliphatic aldehyde with chlorinated 2-position in the presence of a catalyst selected from the group consisting of metallic tin, metallic zinc, zeolite, and Lewis acids. It ensures easy separation of the catalyst from the target trimer and a high yield of the trimer. In addition, the unreacted raw material can be easily recovered.
