Abstract

Abstract : Reactive separation of β-bromoethylbenzene from α-β-bromoethylbenzene mixtures is achieved by the radical polymerization of α-bromoethylbenzene catalyzed by Zn 2+, enabling the separation of molecular isomers with almost identical physical properties. Abstract : A Zn 2+ -induced reactive separation method for the purification of β-bromoethylbenzene from α-β-bromoethylbenzene mixtures is discovered, where the selective decomposition of α-bromoethylbenzene follows a radical mechanism. Zn 2+ facilitates the homolysis of the C–Br bond of halohydrocarbons with benzyl bromide, enabling the separation of the corresponding isomers with almost identical physical properties.
