Three step synthesis of esters of 1,4-butanediol and higher fatty acids from 1,4-dichloro-2-butene as side- product of chloroprene manufacturing process Chemistry

Abstract

The method for producing esters of 1,4-butanediol from 1,4-dichloro-2-butene as by-product of chloroprene production is developed. The synthesis comprises of the steps of dichlorobutene hydrolysis, hydrogenation of the resulting butenediol and esterification of the resulting butanediol, with higher carboxylic acids, i.e. stearic, oleic and palmitic. The esterification reaction is carried out in the presence of acid catalyst without solvent or in solvent toluene. The corresponding esters are defined by their physical and chemical constants.
