Abstract
A method for manufacturing ionic liquid compositions by use of a two-step process which includes the contacting, under first reaction conditions, an amine compound with a hydrogen halide that is preferably in the gaseous form to provide a first reaction mixture. The first reaction mixture is then contacted, under second reaction conditions, with a metal halide compound to form the ionic liquid end-product.
