Electric Literature of 97925-43-4, 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, 97925-43-4, 4-Bromoisoxazole, introducing its new discovery.
A 6 – bromo – 4 – chloroquinolin preparation method (by machine translation)
The invention discloses a 6 – bromo – 4 – chloroquinolin preparation method, in order to 4 – bromophenyl, propiolic acid ethyl ester, phosphorus trichloride as the raw materials, through a three-step reaction to obtain the target product 6 – bromo – 4 – chloroquinolin. The invention has simple operation, environment friendly, comprehensive yield is 70% or more, than the existing 26 – 42% yield, with a remarkable enhancement, greatly reduces the production cost of the existing drugs, is suitable for industrial scale production. (by machine translation)
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 97925-43-4. In my other articles, you can also check out more blogs about 97925-43-4
