| Abstract: | Glycerol Monolaurate(GML) was prepared through hydroxyl protection and GML with 98% content was further produced by purification.The effects of different factors on the reaction were discussed by orthogonal experiment method.The optimum condition were found that mole ratio was 3:1,0.15%P-toluene sulphonic acid was served as catalyst,synthesis temperature was 240 ℃ and reacting time was 2 h.Moleeular distillation was used to purify crude product containing GML and the content of GML in products was determined by periodate oxidation,finally more than 98% purity of GML products was achieved. |
