Abstract: Dodecyl polyglucoside was synthesized by glucose and dodecanol using P-toluenesulfonic acid as catalyst. The effects catalyst type, proportion of material, reaction temperature and pressure were discussed in this paper. The most appropriate reaction conditions: mole ratio of laurel alcohol and glucose 6:1, mass of ratio of P-toluenesulfonic and glucose 0.008:1, reaction temperature 120°C and reaction pressure 5.0kPa.

Abstract: On the basis of the study of green surfactant alkyl polyglucoside that was synthesized from starch or glucose and fatty alcohol by direct method, the reaction mechanism was discussed and the macroscopic reaction kinetics model was proposed and established. The kinetics model between the concentration of glucose(CA) and reaction time (t) was as follows: ln(CA—0.00025) = —(Kt+2.08). The method of establishing kinetics model can be popularized to the kinetic study of other alkyl polyglucoside.
