Abstract
FIELD: organic chemistry. SUBSTANCE: process for recovery and purification of divinyl from divinyl containing hydrocarbon mixtures comprises extractive distillation using acetonitrile as solvent in the presence of polymerization inhibitors and subsequent desorption divinyl form the solvent. The solvent comprises organic and inorganic basic-type substances such as ammonia. The process in carried out in the presence of cyclohexane. EFFECT: more efficient recovery and purification process.
