Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 497-25-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-25-6, in my other articles.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 497-25-6, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2

In the study of the effects of auxochromes on azomethine dye color, an oxazolidinone ring in the acceptor portion of the dye was useful both as a masking group for preparation of the electron-donating hydroxyethyl group, and as an electron-withdrawing auxochrome. In the case of m-aminophenol derivatives coupled with p-phenylenediamine, there was a 15 nm bathochromic shift relative to the parent azomethine of the series (PPD-MAP)3 and a 30 nm bathochromic shift relative to the azomethine formed from PPD and AHT, which contains an electron-donating group. However, unlike many electron-withdrawing groups, the oxazolidinone group does not significantly slow the rate of oxidative coupling of the MAP derivative with the primary intermediate to form the azomethine dye; it was about 70% of that for PPD with AHT, making the oxazolidinone-containing MAP a potentially effective oxidation dye intermediate. The effect on color of an oxazolidinone moiety in the acceptor portion of an azomethine formed with a 4,5-diaminopyrazole as the primary intermediate was similar in the magnitude of the bathochromic shift. Finally, including an auxochrome (phthalimide) that is electron-withdrawing in the acceptor portion of the azomethine, but which has decreased overlap with the pi-system of the chromophore due to twisting out of plane caused by steric interactions, results in a significant hypsochromic shift.
