This study investigated how carbon monoxide (CO) and dimethyl ether (DME), at concentrations of 0.5–5%, impact the bubble points of CO2 streams compared to pure CO2 at equal temperatures. Experiments were conducted from 247.15 K to near-critical conditions using constant composition expansion methods. The measurement uncertainties were 0.14 K and 0.03 MPa for the temperatures and pressures, respectively, and the composition uncertainties were 0.0009 and 0.0011 mol/mol for CO2–CO and CO2–DME systems, respectively. Results showed that CO had a greater effect on the bubble points of CO2 than DME, attributed to CO’s lower molecular weight. In contrast, DME caused a negative deviation from pure CO2 vapor pressures due to its heavier molecular weight. Model validations using the Peng–Robinson and Multi-Fluid Helmholtz Energy Approximation equations of state revealed that both provided accurate predictions, with MFHEA outperforming PR, achieving deviations below 2.5%. These findings indicate that noncondensable gases like CO increase the risk of two-phase flow during CO2 transport, particularly at low temperatures, emphasizing the need for careful impurity management in CCUS systems.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 2","pages":"1004–1012 1004–1012"},"PeriodicalIF":2.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.jced.4c00606","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And its liquid–liquid equilibrium (LLE) data of the ternary system of TFE + water + ILs were determined at 308.15 K and 101.325 kPa. The results showed that the selected ILs were able to achieve effective separation from a phase equilibrium point of view. Subsequently, the NRTL model was used to correlate the liquid–liquid equilibrium data obtained from the experiment to obtain the binary interaction parameters of the system. In addition, the σ-profiles of TFE, water, and related cations and anions of ILs were calculated, then the strength of the extraction ability for the adopted ILs was demonstrated by the interactions.

It was observed that in all these solvents, solubility increases as the temperature rises. At 298.15 K, the molar solubility sequence in the solvents is as follows: cyclopentanone > cyclohexanone > ethyl formate > methanol > ethyl acetate > butanone > methyl acetate > acetone > n-propanol > ethanol > 2-pentanone > n-butanol > isobutanol > isopropanol > isopentanol > n-pentanol > acetonitrile. The solubility data obtained from experiments were fitted using four models: the modified Apelblat model, the Buchowski–Ksiazaczak λh model, the NRTL model, and the Wilson model, all of which demonstrated a good fit. The modified Apelblat model yielded the most accurate correlations, as indicated by the lowest average ARD and RMSD values. Furthermore, using the Wilson model, the thermodynamic properties of the mixing process of 2-aminopyrimidine in the chosen solvents were calculated, revealing that the mixing was spontaneous and primarily driven by entropy. The results of this study provide valuable insights for the purification, crystallization, and industrial application of 2-aminopyrimidine and similar compounds.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 2","pages":"1096–1108 1096–1108"},"PeriodicalIF":2.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143397315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the measured speed of sound, density, and viscosity of liquid mixtures in the entire range of mole fraction. The trend in the acoustical and volumetric parameters for the four mixtures indicates that NHA systems show moderate interactions, while CHA systems show weak interactions. FTIR spectra of the mixtures establish the presence of a hydrogen bond between amine and ether. DFT study reveals the presence of various noncovalent interactions (NCI) through NCI and RDG plots, and the strength of interactions was compared using interaction energy. The interactions in DPE systems are weak due to steric interactions. The present work successfully correlates the results obtained on noncovalent interactions through DFT study and their influence on the bulk properties of liquid mixtures observed through acoustical study.

Herein, the vapor–liquid equilibrium (VLE) data (T, xi, and yi) of binary systems containing VC, FEC, and CEC were determined to avoid inter/intramolecular polymerization using recirculation still at 0.4 kPa. The experimental data were then correlated and predicted using the nonrandom two-liquid (NRTL), Wilson, and UNIQUAC models, revealing a close agreement between the experimental and model-calculated data. The Gibbs free energy (GE/RT) calculations showed positive deviations from the ideal behavior for the VC + FEC and VC + CEC binary systems, whereas the FEC + CEC system exhibited negative deviations, with the maximum excess Gibbs free energy observed near equimolar concentrations. A thermodynamic consistency test confirmed the reliability of the data.
