Synthesis of Nonenoic acid from Oenanthic aldehyde by Modification of Knoevenagel-Dobner

用Knoevenagel－Dobner改良法[1]由正庚醛合成壬烯酸，确定了适于工业生产的催化剂及其用量和反应时间，并解决了产品的后处理问题，获得了较满意的产率。

In this article, nonenoic acid is synthesized from oenanthic aldehyde by modification of Knoevenagel Dobner. Appropriate catalyst for commercial production, its used ammonnt and reaction time are determined. The problem of post-treatment of the products is a1so solved and a satis factory yield is gained.
