Investigation of the Oxidative Chlorination Process of Butylene-Based Organic Compounds

Abstract

This study investigates the features of low-temperature liquid-phase oxidative chlorination of butylene elastomer in the presence of the HCl–H₂O₂ system. Hydrochloric acid (HCl) was used both as a chlorinating agent and catalyst, while perhydrol (a concentrated aqueous solution of hydrogen peroxide) acted as the oxidizing agent. The mechanisms of formation of the active chlorinating complex, as well as the influence of temperature, reagent concentration, and process duration on the degree of chlorination and the properties of the final product, were examined. It was shown that the HCl–H₂O₂ system provides efficient chlorination of the elastomeric matrix without significant destruction of the polymer chain. The obtained results confirm the перспективность of the low-temperature liquid-phase method for producing modified butylene elastomers with improved physicochemical characteristics.
