ABSTRACT APG-12 was synthesized from n-dodecyl alcohol and glucose in catalysis system of p-Toluenesulfonic and phosphoric acid. Using the method of direct glycosidation, this paper discusses the impact of raw material ratio, catalyst dosage and reaction temperature on the synthesis. It is concluded that the synthesis of APG-12 best reaction process condition is the molar ratio of alcohol and glucose 7:1; the reaction temperature is 115℃ and the amount of catalyst is 1.3%, controlling the reaction pressure in 3 - 4 kPa. The resulting products are analyzed by infrared spectroscopy.
