Crystalline | [Purification Methods]
Crystallise HEDTA from warm H2O, after filtering, by addition of 95% EtOH and allowing to cool. The crystals, collected on a sintered-glass funnel, are washed three times with cold absolute EtOH, then again crystallised from H2O. After leaching with cold H2O, the crystals are dried at 100o under vacuum. [Spedding et al. J Am Chem Soc 78 34 1956, Beilstein 4 IV 2449.] |
