烯醇酯是合成高分子化合物的单体,较早由快烃与羧酸反应得到,1944年Bedoukian用醋酸钾为催化剂由异丁醛与乙酐反应得到乙酸异丁烯酯,Gwynn等在硫酸、磷酸等催化下由乙烯酮与酮反应合成了乙酸烯醇酯。我们曾由环戊酮、环己酮在硫酸铁催化下合成了环烯醇酯。本文在合成反应中改用硫酸铜为催化剂时提高了烯醇酯的产率。
Enol ester is a synthetic polymer monomer, the earlier by the reaction of fast hydrocarbons and carboxylic acid obtained in 1944 Bedoukian potassium acetate as a catalyst from isobutyraldehyde and acetic anhydride reaction of isobutyl acetate, Gwynn other sulfuric acid, phosphoric acid Under the catalysis, vinyl acetate and ketones were synthesized by the reaction of ketene and ketones. We have been cyclopentanone, cyclohexanone catalyzed by ferric sulfate cycloalcohol ester. In this paper, the use of copper sulfate as a catalyst in the synthesis reaction increased the yield of enol ester.
