Abstract: In this article, we synthesise dodecyl-polyglucosides by using a complex catalyst and through the direct reaction of glucose and laurel alcohol and optimize the technological datum. The proper reaction conditions:reaction pressure 4.05kPa, reaction temperature 120℃, mole ratio of laurel alcohol and glucose 5:1, mass ratio of complex catalyst and glueos 0.008:1, are obtained. There is further discussion on the active mechanism and application properties of the APG.

Key words: alkyl polyglucoside, surfactant, synthesis method, complex catalyst
