Abstract

Abstract Propylene dimerization has been studied in a biphasic system formed by [Ni(MeCN) 6][BF 4] 2 dissolved in 1-butyl-3-methylimidazolium organochloroaluminate ionic liquid (IL). The activity and dimerization selectivity show a high dependence on the reactional parameters and evidence of interfacial phenomena feature has been obtained. The isomerization of C 6 olefins could be minimized to 13% using a control of dimerization temperature and propylene pressure.
