| 摘 要： | 采用液相催化氧化乳酸，乳酸选择性地转化为丙酮酸的新方法，丙酮酸收率可达５８．２％，讨论了反应时间、反应温度、ＰＨ值及Ｐｂ添加量对丙酮酸收率的影响。结果表明，当Ｐｂ／Ｐｄ（原子比）为０．４ＰＨ值为８，反应温度控制在９０℃左右，反应时间控制在３．５ｈ左右时，丙酮酸收率最高。

| Abstract: | A new method in which lactic acid was oxidized by liquid phase catalysis and selectively converted to pyruvic acid with yield up to 58. 2% was introduced. The effects of reaction conditions such as reaction time, reaction temperation, pH, and the amount of Pb added to Pd/C catalyst on the yield of pyruvic acid were discussed. The result shows that the highest yield can be obtained when Pb/ Pd is 0. 4(atom ratio), pH is 8, the temperature is about 90 C ,and the time is 3.5 h. |
