Abstract

PURPOSE: To obtain the title substance in high purity and recovery, by extracting the crude substance vitamin E nicotinate dissolved in an aliphatic hydrocarbon solvent with a lower alcohol, hydrochloric or sulfuric acid, and water, through the liquid-liquid contact.
CONSTITUTION: Crude vitamin E nicotinate (A) is dissolved in an aliphatic hydrocarbon solvent, e.g. hexane, and extracted with a lower alcohol, e.g. methanol, hydrochloric or sulfuric acid, and water. The nicotinate (A) as a hydrochloride or sulfate, extracted into the lower alcohol layer, is separated, and an alkaline substance, e.g. sodium hydrogencarbonate, is added to the alcohol layer to separate the upper layer of (A).
EFFECT: Very simple treating operations.
USE: Peripheral vasodilators.
