Abstract
New Supported Ionic Liquid Phase (SILP) materials on magnesium oxide-silica (MgO-SiO2) and magnesium oxide-silica/lignin (MgO-SiO2/lignin) supports were obtained. The new SILP materials contain imidazolium, pyridinium, phosphonium and sulfonium cations and methylsulfate as well as bis(trifluoromethylsulfonyl)imide anions. The obtained systems were subjected to detailed physicochemical characterization by: XRD, SEM-EDX, elemental analysis, thermogravimetric measurements, IR spectroscopy and particle size determination. The adsorption properties of both, the supports and the obtained SILP materials, were additionally determined. The catalytic activity and possibility of reusing the obtained SILP systems were confirmed in the hydrosilylation reaction of 1-octene with 1,1,1,3,5,5,5-heptamethyltrisiloxane.
