Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 623-47-2, Name is Ethyl propiolate, SMILES is C#CC(OCC)=O, belongs to esters-buliding-blocks compound. In a document, author is Russo, Vincenzo, introduce the new discover, Recommanded Product: Ethyl propiolate.
Intraparticle diffusion model to determine the intrinsic kinetics of ethyl levulinate synthesis promoted by Amberlyst-15
Levulinic acid and its esters are considered very versatile chemical compounds used for a wide range of derivatives. Traditionally ethyl levulinate is synthesized in batch reactors, using homogeneous catalysts (H2SO4, H3PO4). Several investigations were reported on solid acid catalysts, as zeolites, sulfated oxides, sulfonic ion-exchange resins. Amberlyst-15 showed high potentials: to design a continuous reactor, it is necessary to investigate the stability of the catalyst and the kinetics of the reaction. In the present work, we demonstrated that the resin is stable for more than 5 days. Kinetic and mass transfer phenomena were studied, evaluating the partition and take-up of the used resin when put in contact with reactants and products. Two different samples of Amberlyst-15 were used, characterized by different size, demonstrating that bigger particles lead to higher intraparticle diffusion limitations. (C) 2020 Elsevier Ltd.

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 623-47-2 is helpful to your research. Recommanded Product: Ethyl propiolate.
