Description
Summary:The main features of dimerization of vinylarenes, such as styrene, α-methylstyrene, β-methylstyrene, p -methylstyrene, p -methoxystyrene, p -methoxy-β-methylstyrene, m -chlorostyrene, and m -nitrostyrene used as an example, over zeolite catalysts were studied, and the high activity and selectivity of these catalysts in the reaction was shown. For styrene and α-methylstyrene, the vinylarenes having the largest production volume, catalysts that hold promise for industrial application were developed. Conditions for the selective linear dimerization (85–93%) and cyclodimerization (85–98%) of styrene and α-methylstyrene at a high conversion (100%) were determined.
