Chemical Research Letters, April 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 519-73-3, Name is Triphenylmethane, molecular formula is C19H16, Quality Control of Triphenylmethane, belongs to isothiazole compound, is a common compound. In a patnet, author is Shen, YH, once mentioned the new application about 519-73-3.
4-methyl-5-hydroxy-ethyl isothiazole stearic ester(HISE) was synthesized and characterized by FTIR spectroscopy, H-1 NMR and MS. The monolayer-forming ability of HISE was studied in subphases with different pH values using isotherms of surface pressure-area per molecule (pi-A). It was observed that the collapse pressure and the film-forming ability of the monolayers of HISE increased gradually as pH values ascended. Research of differentiated pi-A curves (dpi(/dA – A) indicated that there were one or two phase change points during the compressing process, and the incompressibility and the stability of HISE monolayers on alkalescent subphases were better than on acid subphases.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. In my other articles, you can also check out more blogs about 519-73-3. Quality Control of Triphenylmethane.
