Reaction Conditions

Reaction Steps

The obtained catalyst was pulverized into 40-80 mesh. 15 g of the pulverized catalyst was placed in a slurry reactor as mentioned above, 100 g of tetrahydrofuran, 3 g of acetic anhydride and 1 g of acetic acid were added. The temperature of the reactor was raised to 50° C. and reacted for 90 minutes. After the completion of the reaction, the catalyst was removed from the mixture by filtration, and the unreacted tetrahydrofuran was recovered by reduced distillation. Polytetramethylene ether acetate with a number average molecular weight of 1927 and a Mw/Mn=1.89 was obtained. The yield was 29%.
