ABSTRACT:
Tocopherols are isolated from vegetable oil distillates and other saponifiable substances in which tocopherols are naturally present, by saponification in an alcoholic medium, followed by metathesis with a zinc halide. The resulting zinc salts of fatty acids are readily precipitated out of solution without mechanical granulation or the addition of powdering agents, leaving the tocopherols in alcoholic solution from which they are readily recovered. The sterols and glycerol are also recoverable for use in other applications.
