Under microwave irradiation, with dimethypyridine-2,6-dicarboxylate and hydrazine hydrate as raw materials, 2,6-pyridine dicarboxylic hydrazine was produced. At the same time, the influence factors of production rate, such as microwave radiation time, reaction power, the amount of dimethypyridine-2,6-dicarboxylate and hydrazine hydrate was further explored. Through the orthogonal experiments, better technology conditions were found which make the synthetic process turn from the new type of microwave technology. 展开更多
