Firstly, the potential energy surfaces of the carbon and oxygen atoms in CO₂ attacked by H radical are calculated using density functional theory (DFT), and the C─H mechanism is proposed by coupling the new paths with the simplified mechanism. Secondly, a constant volume combustion chamber (CVCC) experiment platform is set up, and the flame images are captured under four combustion atmospheres (air, 50% CO₂/50% O₂, 47% CO₂/53% O₂, 39% CO₂/61% O₂). Finally, the reaction sites of CO₂, the free energy barrier, the temperature sensitivity, the species concentration changes, the flame temperature cloud diagrams, and the combustion flame length (CFL) are analyzed. The results show that the C─H mechanism is suitable for studying the combustion characteristics of DSF under CO₂/O₂ atmosphere and the maximum error of CFL is 6.93%. There are two reaction paths for CO₂+H•→CO+•OH at high temperature and pressure, and the free energy barriers for binding to carbon and oxygen atoms are 26.71 kcal/mol and 11.07 kcal/mol, which indicates that Path 1 is more likely than Path 2.</p>\u0000 </div>","PeriodicalId":13894,"journal":{"name":"International Journal of Chemical Kinetics","volume":"58 10","pages":"729-743"},"PeriodicalIF":1.7,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148816516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After that the excitation properties of the first ten excited states of the molecules and the UV-vis spectral characteristics under various external electric fields are studied using the TD-SCF method with the above basis set. With the enlargement of the external electric field, the Cr─Cl bond length rises and the dipole moment reduce and then increases. Nevertheless the molecular energy and energy gap show the same trend. In aspects of charge distribution, the electropositivity of the Cl atoms decreases. When the electric field reaches F = −0.02a.u., the charge changes from positive to negative. The infrared spectra of the molecules occur varying degrees of red shift and blue shift and the UV-vis spectra occurs blue shift. The excitation energy, excitation wavelength, and oscillator strength all change significantly. For dissociation, greater energy and external force are required. Therefore, dissociation can occur under a stronger intensity of the external electric field. Using the DET/PBEPBE/DEF2TZV method, the potential energy surfaces of the 1Cr─2Cl and 1Cr─3Cl bonds continuously decrease by applying external electric fields of intensities, thereby achieving the purpose of stepwise dissociation.

The H-atom abstraction reactions by NH₂ radicals from fuels are crucial in the combustion process of ammonia and fuel mixtures. In this work, the kinetics of H-atom abstraction reaction by NH₂ radicals from C₁–C₄ alcohols and ethers are systematically studied. Quantum chemical calculations at the QCISD(T)/CBS//M06-2X/6-311++G(d,p) level were performed to optimize geometries and compute vibrational frequencies for all relevant species. Single-point energy was determined using QCISD(T)/cc-pVDZ, and QCISD(T)/cc-pVTZ level of theories, with basis set corrections using MP2/cc-pVDZ, MP2/cc-pVTZ, and MP2/cc-pVQZ methods. One-dimensional hindered rotor potentials were obtained with 10° increment using M06-2X/cc-pVTZ method. High-pressure limit rate constants for all reaction channels were calculated by using Master Equation System Solver with conventional transition state theory over a range of temperature (300–2000 K).

The kinetics were studied in the presence of perchloric acid, which served as the proton source. The micelles of sodium dodecyl sulfate (SDS) and Triton X-100 (TX100) were found to inhibit the rate of hydrolysis. In contrast, water-soluble polymers, such as polyvinyl alcohol (PVA) and polyethylene glycol (PEG), accelerated the reaction rate at lower concentrations, producing a peak-like plot of the rate constant versus polymer concentration. This inhibition is attributed to the partitioning (or solubilization) of the lipophilic CFA substrates into the less polar core of the micelles. This sequestration separates the CFA from the high concentration of the hydronium ion (H₃O⁺) in the bulk aqueous phase, thereby decreasing the local concentration of reactants at the reaction interface and reducing the effective rate constant. At low polymer concentrations, an acceleration of the hydrolysis rate was observed, leading to a peak-like profile (rate maximum) in the plot of the observed pseudo-first-order rate constant versus the polymer concentration. This initial acceleration is may be due to a combination of electrostatic and non-covalent interactions (e.g., hydrogen bonding) between the polymer segments and the reactants, effectively increasing the local concentrating of CFA and (H⁺) ions in the vicinity of the polymer chain. The subsequent decrease in the rate constant values after the maximum is attributed to the formation of polymer-micelle-like aggregates that sterically hinder the reaction. The micellar rate constant values were treated using the pseudo-phase model from which the binding constant (K_s) for CFA into the micellar pseudo-phase and the micellar rate constant values (k_m) were determined through the iterative method.</p>\u0000 </div>","PeriodicalId":13894,"journal":{"name":"International Journal of Chemical Kinetics","volume":"58 10","pages":"797-804"},"PeriodicalIF":1.7,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148816549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
