PREPARATION OF CAFESTOL BY SELECTIVE HYDROGENATION OF ITS MIXTURE WITH KAHWEOL

摘要

A process for the preparation of cafestol from kahweol wherein the kahweol is hydrogenated in the presence of a partially deactivated palladium catalyst on a calcium carbonate or active carbon support conditioned by lead. A process for preparing a mixture of cafestol and kahweol by treating coffee oil with anhydrous methanol in the presence of a basic catalyst is also disclosed.
