HCID 7918Acetic AnhydrideSolvent

Procedure

A solution of the diacid prepared in Example 3 (7 g, 0.034 mole) in 18 g of acetic anhydride was refluxed for 3 hours producing a light brown solution. The reaction mixture was concentrated in vacuo to the product as a syrup. This syrupy anhydride may be used without further purification or purified by distillation.
