APG-12 was synthesized from n-dodecyl alcohol and glucose in catalysis system of p-toluenesulfonic and phosphoric acid by using the method of direct glycosidation.The impact of raw material ratio, catalyst dosage and reaction temperature on the synthesis was investigated. The results show that the best synthesis conditions are as follows:the molar ratio of alcohol and glucose 7: 1,the reaction temperature 115℃,the amount of catalyst 1.3%, the reaction pressure 3~4 kPa.At last, interfacial tension and emulsifying properties of APG-12 were determined and evaluated. The results show that APG-12 performance is better than C12 linear LAS and OP-10, its emulsifying properties is more stable when concentration is over 1.5 g/L.
