Purification Methods
It crystallises from EtOH, *benzene, n-hexane, n-heptane or pet ether. It is best purified by sublimation at 120-130o/20mm. Store at 0o, in the dark. It turns green in the presence of light and on long standing in the dark and sublimation leaves the dark-coloured material behind. [Albert et al.
