[Uses]

(±)-Camphoric acid anhydride (1,8,8-Trimethyl-3-oxabicyclo[3.2.1]octane-2,4-dione) may be useful in the synthesis of aliphatic-aromatic copolyesters.
[Uses]

1,8,8-Trimethyl-3-oxabicyclo[3.2.1]octane-2,4-dione could be useful for the syntehsis of aliphatic-aromatic copolyesters, and camphoric acid-?based acylhydrazone compounds.
[Purification Methods]

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.]
