The apparent thermodynamic properties of the ATC dissolution process including Gibbs free energy (ΔG°sol), enthalpy (ΔH°sol) and entropy (ΔS°sol) were calculated. The ATC solubility in various concentrations of the anionic, cationic and non-ionic surfactant was explored. The drug is most efficiently dissolved in sodium lauryl sulphate (SLS).

The aim of this work is to examine the solubility of ATC in ethanol and water mixtures at room temperature and to study the effect of various concentrations of Tween 80 and benzalkonium chloride (BAC) on drug solubility in aqueous mixtures of ethanol. ATC shows maximum solubility in ethanol + water mixtures at a ratio of w1 = 0.7 ethanol. The addition of a surfactant changed the drug solubility profile relative to the surfactant type and its concentration. XRD and DSC results indicate that a high concentration of BAC may induce the formation of ATC solvate which influenced the melting point and solubility of the drug.

The thermodynamic properties of the protonated reactions were regressed from the pKa work. In addition, the protonated order of both 3-(Diethylamino) propylamine and 1,3-Diaminopentane were determined using computational chemistry methods owing to their unsymmetrical structures. In addition to the experimental methods, the dissociation constants at the standard temperature (298.15 K) were also estimated using group functional models (paper–pencil) and computational methods. The computational methods include COSMO-RS and computational chemistry calculations. An artificial neural network (ANN) method was employed to model the data by collecting and combining the experimental properties to estimate the missing pKa values. Although the ANN models can provide acceptable results, they depend on the availability of the data. Instead of using the experimental properties, they were generated using software such as Aspen Plus or CosmothermX. The simulated ANN model can also provide very good fits to the experimental constant values.","PeriodicalId":20094,"journal":{"name":"Physics and Chemistry of Liquids","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82488920","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}

The excess parameters (VE,κs E), deviation in viscosity, excess partial molar volumes, ( and ) excess partial molar isentropic compressibility’s ( and ) of the components at infinite dilution were calculated from the densities, speeds of sound, and viscosities at experimental temperatures. The variation of these properties with composition of the mixtures suggests hydrogen bond and charge-transfer complex formation between 2-ethyl-1-hexanol and self-associated primary alcohols. The VE results have been analysed in the light of Prigogine-Flory-Patterson theory. An analysis of each of the three contributions, namely, interactional, free volume and P* to VE shows that interactional contribution was positive for all binary systems. The free volume effect and P* contribution were negative for all the mixtures. Furthermore, the FTIR spectra have been recorded at 298.15 K and found to be useful for understanding the presence of hydrogen bonding between dissimilar molecules in the liquid mixtures.

The translational diffusive motion of the 1-butyl-3-methyl-imidazolium cation was revealed as a function of concentration and temperature. The diffusion coefficients obtained are in reasonably good agreement with molecular dynamics (MD) computer simulations based on a classical potential. The diffusive mobility of the cation dramatically increases when adding acetonitrile. This increase in diffusivity is directly related to a maximum in conductivity of these ionic liquid solutions and might pave the way for new design of electrolytes. The translational motions in pure ionic liquids are too slow to be resolved by our experiment. However, localized motion resembling rotation on a sphere of the measured proton signal could be identified in the pure ionic liquids.","PeriodicalId":20094,"journal":{"name":"Physics and Chemistry of Liquids","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75900978","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}
