The mole fraction solubility of thiourea in 12 monosolvents was determined by the static gravimetric method from 283.15–323.15 K at 101.2 kPa. The solubility increased with the temperature. X-ray powder diffraction analysis was used to characterize the crystal form of thiourea before and after the dissolution equilibrium, and molecular electrostatic potentials were utilized to study the intermolecular interactions. Solubility was also evaluated by the interaction energy. The solvation behavior is primarily influenced by solvent polarity (ET(30)), with additional contributions from cohesive energy density and hydrogen-bonding (HBD/HBA) effects. The relationship between the solubility of different solutes in the same solvent is then discussed by comparing the solubility behavior of N,N′-diphenyl thiourea and thiourea in monosolvents. The solubility data were fitted with the modified Apelblat and Yaws models; both show better results. These findings are relevant for thiourea purification, crystallization, and industrial applications and for structurally related compounds. Therefore, it is necessary to study the solvation behavior of thiourea in different monosolvents to provide sufficient data for the design of its crystallization process.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 5","pages":"2116–2128 2116–2128"},"PeriodicalIF":2.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917102","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 findings displayed that BH becomes more soluble at higher temperature and less soluble with increased mole fraction of water in the binary solvent mixtures. Concurrently, the impact of solvent on the mole fraction solubility of BH in solution was examined by utilizing the KAT model. The findings show that the capability of the solvent to form hydrogen bonds (α) and the cavity term, which reflects the molecular contact energy between solvent molecules, have the greatest influence on the solvent effect for BH.

The integration of ionic liquids (ILs) with conventional H2O/LiBr mixtures aims to overcome the drawbacks of traditional working pairs, including issues like corrosion and toxicity. The corrosion rates of eight ternary IL working pairs were measured under high-temperature conditions. After a preliminary evaluation of short-term corrosion measurements, four working pairs with lower corrosiveness were selected for further thermodynamic analysis. The results indicate that the ternary working pairs containing [EPy][Br] and [BMIM][I] exhibited lower viscosity, but their specific heat capacities were notably lower compared to the working pair containing [EMIM][Ac]. Furthermore, the ternary working pair containing [EMIM][MeSO3] showed significantly higher corrosiveness than the other three pairs. Based on this analysis, the ternary working pair formed by adding [EPy][Br] to the conventional LiBr solution demonstrates greater potential for application in high-temperature AHT systems.","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"70 5","pages":"1843–1857 1843–1857"},"PeriodicalIF":2.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917027","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}

This review focuses on understanding the physicochemical, thermal, and surface behavior of fatliquors and how they affect their performance in leather manufacturing. The viscosity, density, and flow behavior (rheology) play an essential role in how fatliquors work (viz., viscosity and density affect how well fatliquors spread and soak into the leather, while flow behavior determines how easily they can be applied during processing). These behaviors of fatliquors are important because they help to improve leather quality, make it last longer, and ensure the manufacturing process is efficient. Thermal properties, like heat stability and how fatliquors break down over time, influence processing conditions and durability. Surface properties, such as how fatliquors interact with water and adhere to leather fibers, are also key to ensuring good results (i.e., softness and flexibility). Advanced techniques like FTIR, TGA, and SEM have helped to understand better ways. This review also looks at sustainable options for fatliquors such as biobased and eco-friendly alternatives, which can help reduce environmental impacts.
