•Palladium catalysts immobilised on a supported ionic liquid phase were prepared.•Catalysts were tested in Heck reaction in batch and continuous mode reactors.•Two catalysts showed stable performance for several hours on stream.•A catalyst with good stability and excellent selectivity was developed.
Heck reaction of aryl iodides and methyl acrylate was carried out in an X-Cube™ reactor in the presence of supported catalysts. Palladium was immobilised by different methods on silica with covalently grafted ionic liquid moieties. Activity and selectivity of the SILP-Pd (supported ionic liquid phase) catalysts were found to depend greatly on the conditions (such as solvent and additives) of immobilisation. By the proper choice of the methodology used during heterogenisation, a selective catalyst, showing stable performance for hours on stream, was obtained.
