The Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملdetermination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid
چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولThe Kinetics of Tripropylammonium Fluorochromate Oxidation of Mandelic Acids
The oxidation of Mandelic Acids (MA) to the corresponding oxoacids with tripropylammonium fluorochromate (TriPAFC) in aqueous acetic acid has been studied. The reaction is first order with respect to [TriPAFC], [MA] and [H+]. The oxidation of α-deuteriomandelic acid shows the presence of a primary ki...
متن کاملThe Kinetics and Mechanism of Oxidation of the N-Substituted Urea-Titanium (III) Complexes by Iodine (AS I-3) in Ethanol and Acetonitrile
The oxidation of complexes of Ti(III), (TiL6)3+ (L=ur, Meur, DMeur, DEture, N-Bu-ur, and Phur), by iodine as I3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. The enthalpy of activation appears to decrease as ligand's size ...
متن کاملKinetics and Mechanistic Study of Oxidation of Amoxicillin by Chloramine-t in Acid Medium
This spectroscopic study presents the kinetics and degradation pathways of oxidation of amoxicillin (AMOX) by chloramines-T (CAT) in acidic medium at a constant ionic strength of 0.105 mol dm-3 at 298 K. Reaction between AMOX and CAT in acidic medium exhibits 1:1 stoichiometry (AMOX:CAT). The reaction is of a first-order in both [CAT] and [AMOX]. The order with respect to acid concentration was...
