The use of ionic liquids in catalysis is attracting interesting attention in chemical engineering. Supported ionic liquid catalyst (SILCA) compounds consist of immobilized catalytic species (e.g., transition metal particles residing in an ionic liquid layer immobilized on a solid support). In this work, the kinetics of SELCA compounds has been studied in detail and a mechanistic kinetic model, which describes the differences in selectivity and activity of the catalysts that contain different ionic liquids, has been developed.
