The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate(SMILESS: O=S(C1=CC=C2C(/N=N/C3=CC(C)=C(S(=O)([O-])=O)C=C3OC)=C(O)C=CC2=C1)([O-])=O.[Na+].[Na+],cas:25956-17-6) is researched.Application In Synthesis of 1-(4-Chlorophenyl)pyrrolidin-2-one. The article 《Exploring Chemical Kinetics at Home in Times of Pandemic: Following the Bleaching of Food Dye Allura Red Using a Smartphone》 in relation to this compound, is published in Journal of Chemical Education. Let’s take a look at the latest research on this compound (cas:25956-17-6).
In this communication, a remote exptl. activity in chem. kinetics is described, taking into account the quantification based on the optical sensor of a smartphone. The objective pursued herein is to equip students with the appropriate tools and strategies required to empirically determine the parameters of the rate law including reaction orders, rate constant (k), frequency factor (A), and activation energy (Ea). Typical results of the proposed protocol are shown and discussed in the framework of the bleaching reaction of food dye allura red (RD40) and hypochlorite, as a representative example. A graphical approach of the concentration vs time data measured under the exptl. condition where [RD40] ≪ [ClO-] (isolation method) suggests a first-order kinetics with respect to the dye. In addition, the anal. of the pseudo-first-order constant (kobs) shows a first-order relationship with respect to ClO-. In addition, using the two-point form of the Arrhenius equation, values of 3.22 x 107 s/M and 44.55 kJ/mol were obtained for A and Ea, resp. Interestingly, all the kinetic parameters (reaction orders, k, A, and Ea) are on the same order of magnitude as those previously reported in the literature and acquired with more sophisticated and accurate equipment. This experience provides evidence that it is possible to proceed with remote exptl. activities to deepen the collection and anal. of kinetic data during a pandemic.
