Abstract
A Phillips Cr/SiO2 polymerisation catalyst was converted into an ethylene trimerisation catalyst after assembling new active sites on the silica surface in the presence of TAC (1,3,5-triphenylhexahydro 1,3,5-triazacyclohexane) as ligand and CH2Cl2 as solvent. The reaction conditions play a role in tuning the catalytic activity of this system. It is
