Electric Literature of 1698-53-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 1698-53-9, 4,5-Dichloro-2-phenylpyridazin-3(2H)-one, introducing its new discovery.
Disclosed is single phase multi-stage process for preparation of 1-aryl-4,5-dihalo-pyridazones-6 involving the diazotization of an amino aryl compound, e.g. aniline, followed by reduction with sulfurous acid to obtain the corresponding aryl hydrazine which is then reacted at elevated temperatures with a mucohalic acid to obtain the 1-aryl-4,5-dihalo-pyridazone-6.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 1698-53-9. In my other articles, you can also check out more blogs about 1698-53-9
