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, Recommanded Product: 766-11-0, 766-11-0, Name is 5-Bromo-2-fluoropyridine, SMILES is FC1=NC=C(Br)C=C1, belongs to pyridine-derivatives compound. In a document, author is Tanash, Maha, introduce the new discover.
Ruthenium Catalyzed Hydrogenation of Acetophenone: A Kinetic Modeling Study
The heterogeneously catalyzed hydrogenation of acetophenone (AP) was investigated in i-propanolic solution using Ru-5%/Al2O3 as a catalyst. The catalyst was characterized by x-ray diffraction, BET surface area measurements as well as, with respect to its acidity, by Diffuse Reflectance Infrared Fourier Transformation Spectroscopy (DRIFTS) of adsorbed pyridine. The reaction was zero-order in AP with no products other than 1-phenylethanol (PE), acetylcyclo-hexane (AC) and 1-cyclohexylethanol (CE) detected. The overall order of reaction with respect to hydrogen pressure was 2.5 for the total consumption of AP, 2.8 for the formation of AC and 1.7 for the formation of PE. The kinetic results of AC formation could be modeled successfully assuming the adsorption of AP and hydrogen to take place on different catalytic sites (support and metal, respectively). In the case of PE formation (hydrogenation of the carbonyl group), competitive as well as noncompetitive adsorption of hydrogen and AP are believed to take place in parallel and were both drawn to discuss the kinetic results of PE formation.
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 766-11-0 is helpful to your research. Recommanded Product: 766-11-0.
