However, the efficient separation of these compounds remains challenging due to their structural diversity. This study explored the use of aqueous biphasic systems (ABS) composed of poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol), Pluronic 10R5, and different biodegradable ammonium salts (acetate, tartrate, and citrate) for the extraction of phenolic compounds. Phase diagrams were constructed at three temperatures (289.2, 298.2, and 313.2 K) and characterized by the binodal curve, tie-line length, and slope of the tie-line, with phase inversion phenomena observed for the first time in reverse Pluronic-based systems. The system with ammonium citrate exhibited the best performance in terms of extraction efficiency, biodegradability, and pH compatibility, resulting in stable phenolic compound stability. Five model compounds were evaluated, yielding partition coefficients ranging from 3.5 to 6.5 and extractions exceeding 80% in the polymer-rich phase. These findings demonstrate the potential of sustainable ABS as an effective platform for selective recovery processes in lignocellulosic biorefineries.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 8","pages":"3332–3343"},"PeriodicalIF":2.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acs.jced.5c00298","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144826199","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}

It was found that the solubility of MAP increased with increasing temperature and with the mole fraction of water in the binary solvent systems. In this study, the structural characteristics and intermolecular interactions of MAP molecules were analyzed by using the molecular electrostatic potential surface (MEPS) and Hirshfeld surface (HS). Correlation analysis of the experimental solubility data was carried out by the modified Apelblat equation, the van’t Hoff equation, the λh equation, and the Jouyban–Acree model. The relative deviation, mean relative deviation, and root-mean-square deviation were also calculated. The analysis results showed that the modified Apelblat equation was the best correlation model. At the same time, this study also provides a reasonable explanation for the phenomenon of inorganic salt-induced liquid–liquid phase separation in the experiment.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 8","pages":"3412–3427"},"PeriodicalIF":2.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144826175","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}

At 298.15 K, the present results agreed well with literature values at m > 1 mol kg–1. However, at lower molalities, the literature results were found to be scattered, with Vϕ sometimes increasing anomalously with decreasing m, probably due to hydrolysis of Zn2+(aq). No meaningful comparisons were possible at other temperatures, but plots of the standard molar volumes, V°(Zn(NO3)2(aq)), against temperature, closely paralleled those of related nitrate salts.

Where comparisons were possible, the present results were mostly in good agreement with literature data. Greater differences in Ni(NO3)2(aq) and Co(NO3)2(aq) may be due to cation hydrolysis. Heat capacities were well fitted with an extended Redlich–Rosenfeld–Meyer-type equation for HNO3(aq), and Pitzer-type equations for the three salts. Ternary solutions HNO3 + M(NO3)2 (M = Mg, Ni, Co) were measured as functions of solution composition at constant ionic strengths of (6.0–12.0, 12.0, and 10.44) mol·kg–1, respectively.

It was established that ternary solution heat capacities could be predicted from binary component properties alone, either using Young’s rule (based on molar quantities) or an empirical mixing rule based on massic (“specific”) heat capacities; neither requires information beyond the relevant binary solution quantities, i.e., no additional mixing parameters are needed.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 8","pages":"3178–3189"},"PeriodicalIF":2.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144826226","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}

In this work, a high-performance deep eutectic solvent ChCl-AEEA absorbent with choline chloride (ChCl) as a hydrogen bond acceptor (HBA) and aminoethyl ethanolamine (AEEA) as a hydrogen bond donor (HBD) was prepared. The formation process of the ChCl-AEEA was determined by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimeter (DSC); the effects of AEEA proportion in the DES β, water content ωH2O, temperature T, and pressure pCO2 on the CO2 absorption capacity of the DES were investigated. The results showed that the CO2 absorption capacity α of the DES could be as high as 0.8528 mol of CO2/mol of DES (0.3373 g of CO2/g of DES) at 313.2 K and 0.1 MPa when ωH2O was 51.9 wt % and β was 0.8. The corresponding absorption heat was measured to be −48.34 kJ/mol, indicating a low energy consumption for desorption. The absorption capacity of the DES did not change after five absorption and desorption cycles. The absorption of CO2 in the prepared DES was chemical absorption, which was confirmed by FTIR and the 13C nuclear magnetic resonance (13C NMR) spectrum.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 8","pages":"3049–3058"},"PeriodicalIF":2.1,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144826225","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}
