Abstract

This article describes a method for the synthesis of vinyl esters from fruit acids: malic, tartaric, citric and acetylene, as well as the results of a spectrophotometric analysis of the obtained compounds. Process conditions, product yields, and physicochemical properties of the resulting vinyl esters are given. The homogeneous catalytic reaction of vinylation of malic, tartaric and citric acids with acetylene has been studied and the formation of the corresponding vinyl esters has been proven. The mechanisms of vinylation reactions in the presence of acetylene are proposed. In the synthesis of vinyl ethers, the effect of pressure, temperature, and reaction time on the product yield was established.
高压合成果酸乙烯酯的研究
本文介绍了以果酸苹果酸、酒石酸、柠檬酸和乙炔为原料合成乙烯基酯的方法,以及所得化合物的分光光度分析结果。给出了合成乙烯基酯的工艺条件、产率和理化性质。研究了苹果酸、酒石酸和柠檬酸与乙炔的乙烯化均相催化反应,并证实了相应乙烯酯的生成。提出了乙炔存在下乙烯基化反应的机理。在乙烯基醚的合成中,确定了压力、温度和反应时间对产物收率的影响。
