| Abstract: | Catalytic hydrogenation of diacetyl monoxime to tetramethylpyrazine, by the Pd PPh 3 complex generated in situ, was investigated. The effects of reaction temperature, hydrogen pressure, reaction time, solvent, PPh 3/Pd mole ratio and acid on the reaction results have been explored. The results showed from experiments that the conversion of diacetyl monoxime and yield of tetramethylpyrazine increased with increasing the reaction temperature. But the influences of PH 2, PPh 3/Pd mole ratio and amount of acid on the reaction results have the optimum values, which are 1.2 MPa, 5 and 0.86 mole respectively. The conversion of DAM and yield of TMP were 94.69% and 91.81%, under the experimental conditions. WT5HZ] |
