Chemical Properties

white to light yellow crystal powde

Purification Methods

Crystallise the acid from water (18g from 400 mL boiling H2O) and stir vigorously while cooling in order to obtain crystals; otherwise an oil will separate which solidifies on cooling. Dry it in a vacuum desiccator over KOH/H2SO4 (yield 16.4g) as monohydrate, m 88-89o. It crystallises from xylene as the anhydrous acid, m 173o (150-153o). It does not crystallise from *C6H6, toluene, *C6H6/pet ether (oil), or CHCl3/pet ether. [Butler & Cretcher J Am Chem Soc 55 2605 1933, Acs et al.
