USE
Dissolve D(-)-fructose in an equal weight of water (charcoal, previously washed with water to remove any soluble material), filter and evaporate under reduced pressure at 45-50o to give a syrup containing 90% of fructose. After cooling to 40o, the syrup is seeded and kept at this temperature for 20-30hours with occasional stirring. The crystals are removed by centrifugation, washed with a small quantity of water and dried to constant weight under a vacuum over conc H2SO4. For higher purity, this material is recrystallised from 50% aqueous ethanol [Tsuzuki et al. J Am Chem Soc 72 1071 1950]. [Beilstein 31 H 321, 1 IV 4401.]
