Description
Crystallise the anhydride from EtOH. If it contains too much of the acid (by IR), then reflux it in Ac2O, concentrate and collect the crystals, wash them with pet ether and dry them. [Bunton et al J Chem Soc 2918 1963, NMR: Baker & Davis Tetrahedron 24 1663 1968, Beilstein 18 H 400, 401.]
