Occurs in guaiac-resin to the amount of about 70 per cent. The alcoholic mother-liquor from which the guaiacic acid has been precipitated by alcoholic potash,... in the preparation of guaiacic acid, is evaporated, at 30, to a thick syrup, and mixed with absolute alcohol, whereby a little of the potash-salt of guaiacic acid is thrown down. This last body is removed ; carbonic acid is passed into the filtrate ; the liquid, separated from carbonate of potash and mixed with water and a little hydrochloric acid, is heated to drive off the alcohol ; and the resin thereby separated is washed with warm water. On cooling, the resin forms a brittle, brown mass, which is resolved, by treatment with ether, into guaiaconic acid soluble in ether, and guaiac beta- resin insoluble in that menstruum.
