Acetic Anhydride → Ether acetate

Participants

Reaction Conditions

Reaction Steps

The obtained catalyst was pulverized into 40-80 mesh. 20 g of the pulverized catalyst was placed in a slurry reactor, 100 g of tetrahydrofuran, 8 g of acetic anhydride and 1 g of acetic acid were added. The temperature of the reactor was raised to 45° C. and reacted for 90 minutes. After filtration and separation unreacted tetrahydrofuran by reduced distillation, polytetramethylene ether acetate was obtained. The properties of the resultant polymer are listed in Table 1.
