However, large-scale production using oil substrates complicates downstream recovery, resulting in low yields and high production costs. This study investigates aqueous two-phase extraction (ATPE) as an alternative recovery method. Alcohol/salt aqueous two-phase systems (ATPS) were evaluated using ethanol, 1-propanol, and 2-propanol in combination with various anions (phosphate, sulfate, citrate, and tartrate), while varying pH, temperature, and salt concentrations. The 1-propanol/sulfate system achieved the highest MEL recovery of 83.4% in the alcohol-rich top phase. The addition of 2% (w/w) NaCl improved recovery to 86.4%, while 8% (w/w) NaCl decreased MEL recovery. Since U. maydis coproduces cellobiose lipids (CBLs), we demonstrate that an ethanol/tartrate system could effectively separate MELs from CBLs. Oleic acid, a key contaminant, was found to preferentially partition into the top phase, indicating the necessity for further purification. To validate the system, MELs produced by Ustilago maydis were recovered using the 1-propanol/sulfate ATPS, yielding 87.28% recovery. This study is the first to demonstrate ATPE for MEL recovery and separation from coproducts such as CBLs, offering a promising and scalable alternative to conventional purification methods in industrial biosurfactant production.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 9","pages":"3816–3824"},"PeriodicalIF":2.1,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acs.jced.5c00308","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036343","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}

The newly studied ATPSs exhibited an upper phase rich in surfactant and a lower phase rich in salt. An increase in temperature expanded the biphasic region, altered the phase compositions, and increased the tie-line length. Systems containing citrate exhibited larger biphasic regions due to its higher hydration capacity, while Tween 80 promoted greater phase separation than Tween 20, attributed to its higher hydrophobicity. Partitioning studies with rhodamine B and methyl orange showed preferential dye transference to the surfactant-rich phase, with extraction percentages above 98.7% and 99.2%, respectively. When applied to a textile effluent, the formation of ATPSs using the effluent as solvent led to an expanded immiscibility region in tartrate-based systems. Additionally, color removal efficiency remained above 91.52%, regardless of overall system composition or phase mass ratio, demonstrating the practical feasibility of using these ATPSs for the pretreatment of textile effluents.

This study investigated the mass transfer kinetics and thermodynamics of the phase separation absorption process using 1-amino-2-propanol (MIPA)/sulfolane (TMS) biphasic solvents. 13C NMR spectroscopy was employed to analyze the species in different CO2-loaded solutions. The direction and extent of species transfer during the absorption process were elucidated and the phase separation mechanism was explored. CO2 absorption kinetics were studied in a wetted-wall column, and the physicochemical properties and the absorption reaction kinetics data under different experimental conditions were obtained. Results showed the overall mass transfer coefficient (KG) was 1.6 times higher than 30 wt % MEA and twice that of DETA/TMS solution. NMR and kinetic data analysis revealed that phase separation is mainly contributing to the deterioration of the mass transfer process in biphasic solution, reducing the liquid-film mass transfer coefficient (KL) by 63.2% during the phase separation stage. Furthermore, the desorption heats of different biphasic solvents with identical amine concentrations were measured using a microcalorimeter. Findings indicated that TMS did not alter the thermodynamic properties of the solution. Since only the CO2-rich phase is regenerated, the energy consumption is significantly reduced compared to that of MEA.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 9","pages":"3701–3714"},"PeriodicalIF":2.1,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036384","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}

The phase diagrams of the ternary system KHCO3–NaHCO3–H2O are simple, containing one invariant point, two solubility curves, and two crystallization fields (corresponding to KHCO3 and NaHCO3), with no double salts or solid solutions formed. As the temperature increases, the crystallization fields of both KHCO3 and NaHCO3 expand, but the crystallization field of NaHCO3 always remains larger than that of KHCO3. This suggests that in this saturated ternary system, NaHCO3 is more prone to crystallize out. Based on the solid–liquid phase equilibrium experiments, the mixed salt Pitzer parameters (ΨK+, Na+, HCO3–) for the ternary system KHCO3–NaHCO3–H2O at 308.15 and 323.15 K were fitted and calculated. The Pitzer model was further employed to theoretically predict the solid–liquid phase equilibria of this ternary system at 288.15, 308.15, and 323.15 K.

In this work, three ionic liquids: 1-propyl-3-methylimidazolium dihydrogen phosphate ([PMIM][H2PO4]), 1-butyl-3-methylimidazolium dihydrogen phosphate ([BMIM][H2PO4]), and 1-butyl-3-methylimidazolium hydrosulfate ([BMIM][HSO4]) are screened and employed to separate SBAC and SBA azeotropic mixture using liquid–liquid extraction. Ternary liquid–liquid equilibrium (LLE) data at 303.15 K and atmospheric pressure are determined with distribution coefficients and selectivity evaluated, and data reliability is confirmed via Othmer-Tobias and Hand correlations. The experimental LLE data are correlated by the nonrandom two-liquids (NRTL) model, with the consistency of NRTL model parameters verified through the GMcal_TieLinesLL. The underlying separation mechanism is comprehensively elucidated through QC calculations, with ESP mapping, bond length and interaction energy, IGMH analysis, and QTAIM topological analysis, demonstrating that the interaction between ionic liquids (ILs) and SBA is stronger than the ILs and SBAC, among which hydrogen bond plays a dominant role.
