ABSTRACT:
A process for the trimerization of an olefin selected from the group consisting of ethylene, propylene, 1-butene, and mixtures thereof comprising passing the olefin in contact with a catalyst comprising the reaction product of (i) a chromium compound, which will provide active catalytic species under trimerization conditions; (ii) a hydrocarbyl aluminum hydrolyzed with about 0.8 to about 1.1 moles of water per mole of aluminum compound; and (iii) a donor ligand selected from the group consisting of hydrocarbyl isonitriles, amines, and ethers wherein the aluminum to chromium mole ratio is in the range of up to about 200 to one and the ligand to chromium mole ratio is in the range of up to about 100 to one.
