A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, SDS of cas: 1119-97-7, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1119-97-7, Name is MitMAB, molecular formula is C17H38BrN. In a Article, authors is Sen, Pratik K.，once mentioned of 1119-97-7
The effects of cationic surfactants of cetyl trimethyl ammonium bromide (CTAB), tetradecyl trimethyl ammonium bromide (TTAB) and cetyl pyridinium chloride (CPC) on the kinetics of intramolecular general base catalyzed hydrolysis ([OH-] range 0.05-0.1 mol L-1) of phenyl salicylate have been studied at different temperatures. The rate is independent of [OH-] in the studied range. The anionic surfactant sodium dodecyl sulphate (SDS) has no effect on the rate. The presence of small amount of any of these cationic surfactants well below its critical micelle concentration markedly inhibits the rate of reaction suggesting a pre-micellar aggregation between the substrate and surfactant monomers. The kinetic data have been analyzed in terms of earlier reported models (Piszkiewicz’s co-operativity model and Raghavan and Srinivasan’s model) for micellar catalysis. The binding constants between the substrate and the surfactants evaluated from the two models are in good agreement. Three dimensional structure of the pre-micellar aggregate controls the approach of the nucleophile water molecule to the reaction center. The planar structure of the pyridinium head group of CPC provides less steric hindrance to the attacking water molecule that leads to the least enthalpy of activation for CPC among the three surfactants. The association between the negatively charged substrate and the cationic surfactant is favored owing to electrostatic as well as hydrophobic interactions. The binding between the substrate and pre-micelles follows the order: CPC > TTAB > CTAB.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. SDS of cas: 1119-97-7
