Chemical Properties

Powder

Purification Methods

After removing free acid by extraction with cold aqueous Na2CO3, the residue is crystallised from acetic anhydride and dried at 100o. Acetic anhydride converts the acid to the anhydride. It also crystallises from *C6H6 (m 219o) or chlorobenzene (m 224.5-225.5o). [Beilstein 17 H 526, 17 II 495, 17 III/IV 6425.]
