Electric Literature of 652-39-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 652-39-1, molcular formula is C8H3FO3, introducing its new discovery.
The invention discloses a 3 – phthalic acid synthetic method, the raw material 3 – nitrophthalic acid is dissolved by acetyl chloride solvent dehydration is carried out, after the dehydration by the fluorination potassium […], then adding thionyl chloride to remove the by-product generated in the process of fluoro, purification to obtain the target compound 3 – phthalic acid. The invention relates to 3 – nitrophthalic acid as the synthetic 3 – phthalic acid raw material, the raw material is cheap, simple process, high yield; by adjusting the PH of the method, the product from the sulfolane solvent in very good separation out, solves the high boiling point of the solvent is not easily evaporated difficult; using acetyl chloride as dehydration solvent, not only replacing the drug control acetic anhydride, but also reduces the acetic anhydride in the dehydration process of the acetic acid by-product, mild reaction conditions after processing is simple and convenient.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 652-39-1 is helpful to your research. Electric Literature of 652-39-1
