(-)-Dibenzoyl-L-tartaric acid monohydrate Chemical Properties,Usage,Production

  • Chemical Properties white to light yellow crystal powde
  • Purification Methods Crystallise the acid from water (18g from 400 mL boiling H2O) and stir vigorously while cooling in order to obtain crystals; otherwise an oil will separate which solidifies on cooling. Dry it in a vacuum desiccator over KOH/H2SO4 (yield 16.4g) as monohydrate, m 88-89o. It crystallises from xylene as the anhydrous acid, m 173o (150-153o). It does not crystallise from *C6H6, toluene, *C6H6/pet ether (oil), or CHCl3/pet ether. [Butler & Cretcher J Am Chem Soc 55 2605 1933, Acs et al.
