2,5-Dimethyl-2,5-hexanediol Usage And Synthesis

Chemical Properties

white crystalline flakes

Purification Methods

Purify the diol by fractional crystallisation. Then the diol is dissolved in hot acetone, treated with activated charcoal, and filtered while hot. The solution is cooled and the diol is filtered off and washed well with cold acetone. The crystallisation process ia repeated several times, and the crystals are dried under a vacuum in a freeze-drying apparatus [Goates et al. J Chem Soc, Faraday Trans 1 78 3045 1982]. [Beilstein 1 IV 2600.]
