A METHOD OF SUBSTANTIALLY INCREASING THE OXIDATION RATE OF AN ALUMINUM TRIALKYL WHICH COMPRISES ADMIXING AN ALUMINUM TRIALKYL WHEREIN EACH ALKYL RADICAL CONTAINS FROM 2-20 CARBON ATOMS WITH AN INERT HALOGENATED HYDROCARBON SOLVENT, TO FORM AN ALUMINUM TRIALKYL-SOLVENT MIXTURE CONTAINING AT LEAST 80 WT. PERCENT OF SAID INERT HALOGENATED HYDROCARBON SOLVENT, OXIDIZING THE ALUMINUM TRIALKYL BY CONTACTING SAID ALUMINUM TRIALKYLSOLVENT MIXTURE WITH AN OXYGEN CONTAINING GAS FOR A PERIOD OF TIME SUFFICIENT TO SUBSTANTIALLY COMPLETELY OXIDIZE SAID ALUMINUM TRIALKYL TO THE CORRESPONDING ALUMINUM ALCOHOLATE.
