Hydrochloric Acid → HCID 86746190, compound

Natural phosphatide mixtures from soy containing more than 70% phosphatidylcholine (PC) were dissolved in hexane at 1 gm lipid/10 ml solvent. To this solution 6.6 ml of absolute ethanol and 3.3 ml of 0.2N HCl was added and mixed thoroughly at atmospheric pressure and at about 22.5° C.+/- about 2.5° C. Phase formed and were permitted to separate and the lower aqueous phase discarded. The hexane phase was repeatedly washed with ethanol-water, 1:1 (v/v) until the pH in the lower aqueous phase was neutral. The resulting desalted lipids were recovered from the hexane phase by removal of the hexane by rotoevaporation at 35° C. and 100 mm Hg.
