Chemical Properties

white powder

Purification Methods

It is very soluble in H2O, but can be crystallised from a small volume of H2O in small crystals. These are washed with EtOH and dried over H2SO4 at 125o. [Bandrowski Chem Ber 10 841 1877, Lossen Justus Liebigs Ann Chem 272 133 1893, Beilstein 2 H 801, 2 I 317, 2 II 670, 2 III 1991, 2 IV 2290.]
