However, there are lots of factors affecting the yield including the amount of potassium permanganate and sulfuric acid, reaction time, power, 2,6-dimethylpyridine dosage. We made the further research, using orthogonal experiment to find the optimal process conditions. Thus our research changed the synthesis process from a traditional method to a new type of microwave technology.展开更多

The results show that the software can manage intelligently all aspects of the quality analysis and test of ascorbic acid products, uploading timely the data and results of the analysis and inspection to the network and saving it for users, enterprises and quality management, which set up a network of information sharing platform to ensure the authenticity and reliability of measurement results, improving greatly the speed of data processing, saving valuable time, reducing production costs with good economic efficiency and social benefit. It has practical value for ascorbic acid quality analysis test data processing automatically the results of the implementation of intelligent management.展开更多
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,...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

Liquid-liquid continuous biphasic extraction was a new method, and showed the advantage of high extracting contents of total flavone compared with one of the traditional methods. The novel extraction method which is easy to operate and has good reproducibility was much more effective than the traditional one.展开更多
