When using active pharmaceutic ingredients (APIs) to construct DESs, therapeutic DESs (THEDES) were obtained. A series of THEDESs based on fatty acid (FA) have been developed and shown excellent bio-activities, which displayed great potential applications in fields like wound healing, transdermal drug delivery etc. Physical properties, like density, and viscosity etc., are of great importance in practical implementation scenarios, thus, deep insights on the thermodynamic properties are highly desirable. In this work, physical properties, i.e. refractive index, surface tension, density, and viscosity, for a series of matrine and FA DESs were precisely measured. The influence of temperature, HBD composition and alkyl chain length on these properties were further discussed. It has been suggested by the results herein that all explored physical properties displayed a decline tendency with temperature, which may be ascribed to the decrease of H-bonding interaction with temperature. Besides, for each DES, increasing the HBD composition resulted in a decrease of all measured physical properties due to the decrease of molar weight of DES. As to the change of physical properties with alkyl chain length, the conclusions were much complex. The refractive index enhanced with alkyl chain length, while density and surface tension showed obvious decline with alkyl chain length. Moreover, variance of alkyl chain length caused only slight increase of viscosity that may be resulted from the increase of molar weight of DES.</div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"55 9","pages":"2204 - 2217"},"PeriodicalIF":1.3,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394229","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}

This study for the first time revealed the inhibitory effect of caprolactam on the solubility of ammonium sulfate, which provided a thermodynamic basis for the crystallization process.

The density and viscosity of CO2-free and loaded aqueous nEB-PEI1800 solution are measured at the temperatures of (293.15 to 333.15) K and 0.1 MPa. The aqueous solutions with various weight fractions of w = (5, 10, 15, 20 and 30%) are investigated. According to the experimental data, thermal expansion coefficient (αp), viscosity activation energy (Eη) and CO2 diffusion coefficient (DCO2), are calculated. The influence of temperature, nEB-PEI concentration, CO2 loading and modification degree are discussed from the viewpoints of molecular interaction and steric effect. The results reveal that low temperature, high nEB-PEI concentration and high CO2 loading lead to high density and viscosity. Modification degrees have a great impact on the physical properties of nEB-PEI1800 + H2O systems and can reduce the density and viscosity. The density and viscosity values exhibit the decreasing sequence of ρPEI + H2O > ρ0.29EB-PEI + H2O > ρ0.35EB-PEI + H2O ≈ ρ0.22EB-PEI + H2O and ηPEI + H2O > η0.22EB-PEI + H2O > η0.35EB-PEI + H2O > η0.29EB-PEI + H2O, respectively.
