Influence of Preparation Conditions of the Solid Base Catalyst on the Performance of Synthesizing Polyglycerol
Keyword(s):
Different solid base catalysts used for the polymerization of glycerol were prepared by impregnation. Catalyst type and the preparation conditions were optimized on the base of polymerization degree. Results showed: the best catalyst was KF/Al2O3, and optimal condition for catalyst preparation was as follows: loading of 40% KF, calcinations temperature 600°C. The polymerization degree of 5.92 was obtained under the following reaction condition: the amount of catalyst 11.62,reaction temperature 250°C, reaction time 4 h.
