To analyze the interactions between the molecules, the researcher utilized the cubic-plus-association (CPA) model, which takes into account both the physical and association interactions. The maximum deviation observed in the density of the liquid solutions of methyl lactate with 1-heptanol was 0.28%, indicating the effectiveness of the CPA model in accurately modeling the density. Additionally, the researchers calculated the excess molar volumes and deviation in viscosity for the studied liquid mixtures. The analysis of these measurements revealed that the solutions of methyl lactate with 1-alkanols exhibited positive excess molar volumes across the entire concentration range. On the other hand, negative viscosity deviations were observed for the mentioned alkanols. These findings suggest that there are weak intermolecular associations within the liquid solutions, with weaker bond strength observed in higher alkanols.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 11","pages":"1462 - 1475"},"PeriodicalIF":1.4,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10953-024-01389-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141104357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors affecting partitioning in ATPSs, such as molecular weight and polymer concentration, pH, temperature, hydrophobicity, and affinity, are also examined. The article then focuses on the application of ATPSs in protein and enzyme extraction, including continuous processing and scaling-up. The future prospects, challenges, and limitations of ATPSs in this field are discussed, along with the challenges associated with their use in industry. The results section highlights the potential of citrate green salts as an alternative to sulfate and phosphate salts in salt-based ATPSs and the need for more research on using ionic liquids as an additive in ATPS types for protein and enzyme extraction. Overall, this review suggests combining cheap and environmentally friendly materials in ATPSs can be a practical solution for using ATPSs in the industry.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 10","pages":"1 - 35"},"PeriodicalIF":1.4,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886378","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}

Hexen and Nonen primarily act as hydrogen bond acceptors, with Men serving as the principal hydrogen bond donor. After the formation of HDES, the IR absorption peaks of Hexen, Nonen's–NH₂, and Men–OH fused into a wider peak, the ¹H-NMR spectra of Men–OH, shifted to a lower field. Furthermore, a significant redshift approximately 300 cm⁻¹ was detected in the vibrational frequency of the Men–OH functional group when performing density functional theory (DFT) calculations for the HDESs. These results support the development of stronger O–H···N bonds between Hexen/Nonen–NH₂ and Men–OH, and the calculated sum of hydrogen bonding energy was approximately 56 mol·kg^–1, categorizing it as an intermediate-strength hydrogen bond. Both HDESs have ethylenediamine polar heads in their hydrogen bond acceptors, which have chelating characteristics that help them coordinate with transition metal ions. Metal ions such as Cu(II), Co(II), and Ni(II) were successfully extracted from aqueous solutions at a concentration of 10 mmol·L^–1using HDESs. The Cu(II) and Ni(II) extraction efficiencies exceeded 90%, indicating their effectiveness. Notably, even at higher metal ion concentrations (100 mmol·L^–1), the extraction efficiencies of all three metal ions remained consistently below 80%.
