Process for the enhancement of the cycle life of a zinc-chromium based catalyst in the synthesis of 2-methylpyrazine |
| 摘要 |
The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenerated after each cycle of use without substantial loss of activity.
