Abstract
Racemic or optically active D- or L-α-glycerophosphoryl choline solids are prepared from liquid type racemic or optically active D- or L-α-glycerophosphoryl choline using an organic solvent. The solids are produced at a high yield more easily through phase transformation than an existing method using a difference in solubility in a solvent.
