Purification Methods

The diol (~30g) is purified by making into a thick paste with H2O and suspending this in 3L of H2O containing 200mL of EtOH, boiling under reflux for 3hours, cooling to 30o, saturating with SO2, digesting below the boiling point for 1hour and filtering fast through a large hot filter paper. The hot filtrate is poured onto crushed ice whereby the diol (15-20g) separates as colourless needles (m 258o) [Wheeler & Ergle J Am Chem Soc 52 4873 1930]. Recrystallise it from H2O or nitromethane under N2 to avoid oxidation. The dibenzoyl derivative has m 245o (from EtOH). The 5-methoxy-1-naphthol derivative [prepared from the diol in MeOH/HCl (1:30 weight to volume ratio) and set aside at 25o for 9-10days] crystallised from pet ether (m 135-136o) or from CH2Cl2/hexane (needles m 140o) [Bell & McCaffrey Aust J Chem 46 731 1993]. [Beilstein 6 I 477, 6 II 950, 6 III 5265, 6 IV 6554.]
