Masaryka 275, 762 72 Zlín, Czech Republic Abstract. The reaction pathway for the conversion of glycerol into different products, namely glyceraldehyde, glyceric acid, glycolic acid, mesoxalic acid and tartronic acid was studied by means of electrochemistry. Multiple Pulse Amperometry technique was used to control the potential during the electrooxidation reaction. The estimation of the transfer function was realized on the basis of dynamic models for the oxidation reaction. The equations obtained in the s-domain were expressed in the time domain using Inverse Laplace transformation to describe the variation of glycerol and products concentration. 1 Introduction Analysis of reaction products formed during the sustained electrolysis was performed by High The partial oxidation of glycerol via heterogeneous redox Performance Liquid Chromatography (HPLC). Multiple reaction is a process that is carried out under mild pulse amperometry technique was used to control the conditions. This allows the minimization of energy waste potential during the electrooxidation reaction. Proposal of and by-products generation. This process has been a reaction pathway was performed in order to determine intensively studied by several authors [1–7]. In the rate constants, followed by the estimation of the mentioned works, glyceric acid, CO2, hydroxypyruvate, transfer function calculated on the basis of dynamic tartronic acid, mesoxalic acid, glyceraldehyde, or formic models for the anodic oxidation.

  • Carbon Dioxide Production in the Oxidation of Organic Acids by Cerium(IV) Under Aerobic and Anaerobic Conditions
    JCK(Wiley) RIGHT BATCH Carbon Dioxide Production in the Oxidation of Organic Acids by Cerium(IV) under Aerobic and Anaerobic Conditions KARA BUTLER, OLIVER STEINBOCK,* BETTINA STEINBOCK,* NAR S. DALAL Florida State University, Department of Chemistry, Tallahassee, Florida 32306-3006 Received 16 March 1998; accepted 2 June 1998 ABSTRACT: The stoichiometry of CO2 production during the ceric oxidation of various organic acids is measured under conditions with organic acid excess. Measurements utilize a photo- metric methodology. For anaerobic conditions stoichiometries [CO2]produced : [Ce(IV)]reduced of about 0 (malonic acid), 0.5 (e.g., glyoxylic acid), and 1.0 (oxalic acid) are found. Oxalic acid showed an oxygen-induced decrease of CO2 production, while other compounds such as ma- lonic acid increased the amount of produced CO2 or showed no changes (e.g., tartronic acid). In the case of mesoxalic acid the stoichiometry is increased from about 0.5 to 2.0 due to the presence of molecular oxygen. The results are discussed on the basis of simple reaction mech- anisms demonstrating that useful information on reaction pathways and intermediates can be extracted from these simple measurements. ᭧ 1998 John Wiley & Sons, Inc. Int J Chem Kinet 30: 899±902, 1998 The study of oxidation of relatively low molecular and involve numerous organic acids and radicals as weight carbonic acids by metal ions has been an active intermediates [4,7]. A common characteristic, how- area of kinetics [1]. In particular the oxidation of ma- ever, is that most organic acids are oxidized to carbon lonic acid (CH2(COOH)2) and similar compounds by dioxide.

(Submitted: April 12, 2013 ; Revised: November 5, 2013 ; Accepted: November 26, 2013) Abstract - The liquid phase oxidation of glycerol was performed producing fine organic acids. Catalysts based on Pt, Pd and Bi supported on activated carbon were employed to perform the conversion of glycerol into organic acids at 313 K, 323 K and 333 K, under atmospheric pressure (1.0 bar), in a mechanically agitated slurry reactor (MASR). The experimental results indicated glycerol conversions of 98% with production of glyceric, tartronic and glycolic acids, and dihydroxyacetone. A yield of glyceric acid of 69.8%, and a selectivity of this compound of 70.6% were reached after 4 h of operation. Surface mechanisms were proposed and rate equations were formulated to represent the kinetic behavior of the process.

Received April 25, 2018; Accepted May 27, 2018; Epub July 1, 2018; Published July 15, 2018 Abstract: Diabetic mellitus (DM), commonly referred to diabetes, is a worldwide metabolic disorder, which usually causes high morbidity and mortality rates. Especially, DM may result in serious macrovascular problems including cataract. To investigate the underlying molecular mechanism, here we for the first time employed gas chromatogra- phy-time-of-flight mass spectrometry (GC-TOF MS) for an untargeted metabolomics study. Totally 263 metabolites were determined in aqueous humor (AH) samples from 30 patients: 15 for the controls and 15 with DM. Both the heat map and principal component analysis (PCA) plot showed a significantly distinct metabolomics profiles be- tween patients with DM and the controls. Moreover, 20 metabolites were determined to be significantly altered (P ≤ 0.05) in DM patients, some of which were associated with oxidative stress. Metabolic pathway analysis of these significantly different metabolites identified ten most relevant pathways in the group of DM patients when compared with the control group. Among them, three pathways including fatty acid biosynthesis, fatty acid metabolism, and linoleic acid metabolism were the three most significantly influenced pathways (P ≤ 0.05), which probably play key roles in the formation of DM and its complication, cataracts.
