2-Methylpyrazine ammoxidation

In conclusion, research and industrial interest in the ammoxidation of methylpyridine and methylpyrazine is still active. This process could offer a greener alternative to current processes in the production of intermediates for a variety of specialty chemicals, especially in rapidly developing locations such as China where a growing interest in the reaction has been noted [115, 116]. 

The catalyst used for this reaction was similar to that used for ammoxidation of or /io-xylene, namely, V-Sb-0. Again, high ammonia/hydrocarbon feed ratios were needed for optimum results. At 440°C and with an ammo-nia/methylpyrazine ratio between 15 and 20, the 3deld of cyanopyrazine reached 74% with conversion of methylpyrazine of 96%. Best results were obtained with...
