| Abstract: | White needled crystal of β- phenyllactic acid was obtained by catalytic hydrogenation of phenylpyruvic acid in methanol at 70℃ and 3.0MPa for 1h in the presence of Raney-Ni catalyst. The yield and conversion were 91% and 91%, respectively. Infrared spectra and mass spectra of β-phenyl-lactic acid were also discussed. |
