Transesterification of Natural Lecithin Catalyzed by Isopropylamine

Article Preview

Abstract:

The isopropylamine with low boiling point was used for preparing GPC from natural lecithin under mild conditions, it was confirmed as an effective catalyst and the recovery can be combined with the recovery of methanol by distillation. The mechanism of the transesterification reaction was proposed and the experiments obtained the better effect under the conditions of: catalyst content was 2.4% of the total reaction volume, lecithin concentration was 0.05-0.10mol L1 , reaction temperature was 60 °C and reaction time was 260 min.
