DEXTROSE Usage And Synthesis
  • Chemical Propertieswhite, odorless, fine crystalline powder
  • DefinitionChEBI: D-Glucopyranose having alpha-configuration at the anomeric centre.
  • Purification MethodsRecrystallise -D-glucose slowly from aqueous 80% EtOH, then dry it over P2O5 in vacuo. Alternatively, crystallise it from water at 55o, then dry it for 6hours in a vacuum oven between 60-70o/2mm. Its solubilities are: H2O (~50%), EtOH (1.7%). [Hendricks et al. J Am Chem Soc 56 99 1934, Beilstein 1 IV 4302.] [For equilibrium forms see Angyal Adv Carbohydr Chem 42 15 1984, Angyal & Pickles Aust J Chem 25 1711 1972.]
