l?uterung methode

Purify the mandelic acids by recrystallisation from H2O, *C6H6 or CHCl3. [Roger J Chem Soc 2168 1932,Jamison & Turner J Chem Soc 611 1942.] They have solubilities in H2O of ca 11% at 25o. [Banks & Davies J Chem Soc 73 1938.] The S-benzylisothiuronium salts has m 180o (from H2O) and [] D 25 (+) and (-) 57o (c20, EtOH) [El Masri et al. Biochem J 68 199 1958]. [Beilstein 10 IV 564.]
