Paragraph 0050; 0053; 0053; 0054; 0055, (2018/10/19)
The invention relates to a novel synthetic method to synthesize intermediate glycerophosphate from calcium glycerophosphate, comprising the steps: adding glycerol into POCl3 and a catalyst under ice bath, allowing natural restoring to room temperature, stirring to allow reaction for 5-6 h, distilling in vacuum, and collecting glycerophosphate fraction. The catalyst is ionic-liquid-modified silica-supported pyrophosphoric acid catalyst.
