Reaction Steps
A 50:1 mole ratio of ethylene carbonate:monoethylene glycol is heated with stirring under a nitrogen atmosphere for 88 hours at 135° C. using 0.2 percent Na2SnO3.3H2O as catalyst to give 96.6 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 27.6 percent carbon dioxide.
