Popis:	Alkylation of aromatic compounds with various alkylating agents such as benzyl chloride, benzyl alcohol and isopropyl chloride were investigated using ZnCl2 based ionic liquid (ILs) Lewis acid catalysts. Multi-component Lewis acid catalysts of ZnCl2 and ionic liquids such as 1-butyl-3-methylimidazolium bromide, 1-butylpyridinium bromide, cholin chloride and tetrabutylammonium bromide were prepared, supported on silica gel, and compared for alkylation reactions with various alkylating agents. Among the IL-based catalysts, 1-butyl-3-methyl imidazolium-bromide-ZnCl2 and 1-butylpyridinium bromide-ZnCl2 are highly active.
