STUDY OF THE EFFECT OF VARIOUS FACTORS ON THE SYNTHESIS OF VINYL ESTERS OF WINE ACIDS

Abstract

Fruit acids and their vinyl derivatives are widely used as biologically active substances in agriculture, medicine and industry. Adding a vinyl group to the acid molecule to increase its reactive active centers, thereby further increasing its biological activity, is one of the urgent tasks. Potassium-sodium salt of tartaric acid NaKC₄H₄O₆·4H₂O is used in chemical analysis and radio technology under the name of segnet salt. In this paper, complicated vinyl esters of dibasic carboxylic acids, including wine acid, are synthesized in a homogeneous solution of the solvent dimethylformamide in the presence of zinc acetate and AlCl₃-6H₂O catalysts, along with a description of the spectra of the end products.
