Zusammenfassung: | A process for preparation of L-alpha-glycerophosphoryl choline is provided to reduce preparation costs by using an inexpensive starting material and a small amount of ion exchange resin, improve preparation yield and is applied to the industrial scale. A process for preparation of L-alpha-glycerophosphoryl choline represented by the formula(1) comprises the steps of: removing calcium from compounds represented by the formula(2) under acid condition at -10 to 60 deg.C and pH 2 or less to prepare compounds represented by the formula(3); reacting the compounds represented by the formula(3) with compounds represented by the formula(4) in solvent selected from C1-C6 alcohol, C1-C6 ether, C1-C6 ketone and a mixture thereof at 40-120 deg.C and pH 5-10 to prepare compounds represented by the formula(5); crystallizing the compounds represented by the formula(5) by using a crystallizing agent selected from C1-C6 alcohol, C1-C6 ketone and a mixture thereof at 0-25 deg.C; and subjecting the compounds represented by the formula(5) to ion exchange resin so as to remove chlorine ion. |
