A Systematic Review of Enzymatic Kinetics in Microreactors

Catalysts, Journal Year: 2023, Volume and Issue: 13(4), P. 708 - 708

Published: April 7, 2023

Microreactors have become an efficient tool for many enzymatic reactions because the laminar fluid flow within microchannel enables precise process control, rapid mixing, and short residence time. This paper provides a systematic overview of application reaction kinetics mathematical modeling processes in microreactors. Rapid heat mass transfer high surface-to-volume ratio are usually reasons why microchannels proceed faster with higher yields productivity compared to conventional macroreactors. Since there no radial diffusion limitations, microreactors also effective determining kinetic parameters enzyme-catalyzed reactions. By eliminating effect on rate, estimated microreactor closer intrinsic reaction. In this review, advantages disadvantages using highlighted potential their is discussed. Advances result intensification more biocatalytic line offered by microreactors, such as (i) yields, (ii) cleaner improved product profile, (iii) scale-independent synthesis, (iv) increased safety, (v) constant quality output through (vi) accelerated development. Furthermore, excellent studies under specified conditions, enhancing capabilities other methods.

Diastereoselective Electrochemical Coupling of Beta-Nitrostyrenes Under the Current-Constant Conditions

Published: Jan. 1, 2025

The electrochemical coupling reaction of beta-nitrostyrene and 4-chloro-beta-nitrostyrene was reported. This is the first report on beta-nitrostyrenes. Moreover, processes were performed using simplest conditions; constant current (simpler than potential), simple undivided cell, employing non-expensive graphite still electrodes, a green solvent (ethanol), performing at room temperature. First, various cyclic voltammetry experiments, effects potential scan rate pH behavior reactant investigated. Then, conditions such as pH, solvent, type density optimized by examination yield product. pH=6, ethanol steel sheets cathode, rod anode, density=0.97 mA/cm2 (30 mA current). coulometry, number exchanged electrons in this process calculated to help find possible mechanism. After completion reactions, products identified mass spectrometry, FT-IR, NMR methods. It found that only more thermodynamically stable meso configurations are produced, which makes diastereoselective. plausible mechanism, obeyed from EC proposed for reaction, including two-electron transfer reaction.

Esterification of Levulinic Acid to Ethyl Levulinate over Amberlyst-15 in Flow: Systematic Kinetic Model Discrimination and Parameter Estimation

Industrial & Engineering Chemistry Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 13, 2025

An automated reactor platform was developed using LabVIEW to conduct preplanned experiments for the identification of a kinetic model esterification Levulinic acid (LA) and ethanol over heterogeneous Amberlyst-15 catalyst. A Single Pellet String Reactor 1.25 aspect ratio used this study, loaded with 0.1 g 800 μm catalyst spheres, at flow rates 20-60 μL/min, temperatures 70-100 °C, LA feed concentrations 0.8-1.6 M. extensive library power law, Langmuir-Hinshelwood-Hougen-Watson Eley-Rideal models, screened through application general procedure discrimination parameter estimation. The procedure, consisting seven steps, applied investigation different design spaces allowed reformulation models include temperature-dependent parameters, former leading an increase in identifiability latter resulting enhanced fitting. combination experimental data sets including addition reaction product (water) inlet stream incorporation temperature dependence adsorption coefficients' expression led two suitable out 28 candidates (a model), both which accounted water on fitted satisfactorily.
