Reaction Steps

A 100:1 mole ratio of ethylene carbonate:monoethylene glycol is heated with stirring under a nitrogen atmosphere for 121 hours at 135° C. using 0.1 percent Na2SnO3.3H2O as catalyst to give 92.5 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 26.9 percent carbon dioxide.
