L-α-Glycerophosphocholine from Natural Lecithin via Transesterification Catalyzed by Propylamine
Keyword(s):
The propylamine with low boiling point was confirmed as effective catayst for preparing GPC from natural lecithin via transesterification. The catalyst can be separated combined with the recovery of methanol by distillation. Under the conditions of: the catalyst content was 2.4% of the total reaction volume, lecithin concentration was 0.05-0.10mol L–1 , reaction temperature was 60 °C and reaction time was 4 h, the conversion of phosphatidylcholine could reach over 98%.
