Choline derivatives were covalently immobilized on the surface of γ-aminated silica. The obtained immobilized choline derivative was then successfully used for a transesterification reaction to produce glycerophosphocholine (GPC). Fourier transform infrared analysis and thermogravimetric analysis/differential thermal gravimetry indicated that the surface of the γ-aminated silica was covered by choline derivatives and the highest immobilization amount reached mmol/g under optimal conditions. More importantly, the highest yield of GPC reached during transesterification. |
