Abstract-A novel synthetic methods for the efficient and environmentally-friendly production will provide useful inspiration. This report presents a novel method for microwave-assisted synthesis of diazinon with different organic solvents, microwave heating power, heating time, catalysts. The optimal conditions for this synthesis are: 750W for microwave power, 12 min. for heating time, and 0.02% for mole ratio of catalyst DMAP to O, O-diethyl thiophosphoryl chloride and 1, 2-dichloroethane for the best solvent, which can lead the yield of diazinon to 67.86%. When adding repeatedly fresh 2-isopropyl-6-methyl-4-hydroxy pyrimidine for enough times, the yield of diazinon for O, O-diethyl phosphoryl chloride can be as high as 86.54%. With an amazing chemical reaction rate and less waste water discharge, microwaveassisted synthesis is a promising method for green synthesis.
Abstract. The behavior of glycolysis concerning the biochemical reaction was thought to be similar to the oscillatory reaction with glucose being the substrate. The objective of this research is to find a new oscillatory system and study its relevant properties, so new Cu (II)-catalyzed oscillating reaction involved glucose and acetone as the double substrates was investigated systematically. As a function of reaction temperature and concentration of glucose, bromate, and acetone, the features in this novel oscillation system was studied. The results showed that the activation energy reached up to 90.839 KJ/mol and the oxidized product of the double substrates provided the impetus in the course of the new oscillating reaction. A tentative mechanism was considered on the basis of FNK.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
