Metal ion-exchanged montmorillonites were found to be efficient catalysts for the condensation reaction of trimethylhydroquinone with isophytol to afford α-tocopherol in high yield. The condensation reaction proceeded smoothly using 50 w/w% of catalyst in various solvents. The catalyst was easily recovered by filtration of the reaction mixture after the reaction was completed, and could be reused.
