Abstract
According to one aspect of the invention, there is provided the use of an organic ionic liquid in a zeolite-catalysed process, for example an acylation, alkylation, isomerisation or hydrocracking process in which zeolites act as catalysts or catalyst precursors, especially Friedel-Crafts alkylation and acylation procedures.
