| Abstract: | The main physicochemical properties of phenylpyruvates are studied. The results show that the thermal stability of the sodium salt of phenylpyruvate is better than that of the other two phenylpyruvates. The solubility of ammonium salt of phenylpyruvate is much higher than that of the others. The effects of these three phenylpyruvates on the transamination reactions for the production of L phenyalanine are almost the same. |
