In this work, a systematic experimental characterization was carried out on a ternary DES based on ChCl:Gly (1:2) incorporating hydrated metal salts. Systems containing AlCl3·6H2O, MgCl2·6H2O, Mg(NO3)2·6H2O, and CaCl2·2H2O are prepared at metal salt molar fractions ranging from 0.10 to 0.35. Density, viscosity, speed of sound, surface tension, and contact angle are measured over the temperature range of 293.15–343.15 K at atmospheric pressure. Experimental density, viscosity, and speed-of-sound data were correlated using empirical regression models, providing accurate descriptions of their temperature dependence and enabling predictive capability. Surface tension and contact angle measurements are used to assess interfacial behavior and wettability, revealing clear dependencies on DES composition and substrate nature. Overall, this work provides a consistent data set of bulk and interfacial properties for these choline chloride:glycerol:metal salt hydrated DES systems, contributing to improved structure–property understanding and supporting their rational design and application in process-oriented systems. application/pdf eng ACS Publications Journal of Chemical & Engineering Data. 2026, V. 71, n. 7, p. 2914-2931 https://doi.org/10.1021/acs.jced.6c00151 Atribución 4.0 Internacional http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Thermodynamic properties Anions Solvents Salts Metals Disolventes Sales Salts Solvents Tailoring Deep Eutectic Solvents: The Role of Hydrated Metal Salts in Modifying Structural Organization and Macroscopic Performance info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Journal of Chemical & Engineering Data 71 7 2914 2931 THUMBNAIL Perez-jmed_2026.pdf.jpg Perez-jmed_2026.pdf.jpg IM Thumbnail image/jpeg 5375 https://riubu.ubu.es/bitstream/10259/12015/4/Perez-jmed_2026.pdf.jpg e0036b54d77bddb8ddb5969b0e222671 MD5 4 LICENSE license.txt license.txt text/plain; charset=utf-8 998 https://riubu.ubu.es/bitstream/10259/12015/3/license.txt aa90105e1c90a1b4fe810649aa967b7d MD5 3 CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 908 https://riubu.ubu.es/bitstream/10259/12015/2/license_rdf 0175ea4a2d4caec4bbcc37e300941108 MD5 2 ORIGINAL Perez-jmed_2026.pdf Perez-jmed_2026.pdf application/pdf 4196156 https://riubu.ubu.es/bitstream/10259/12015/1/Perez-jmed_2026.pdf d38da68519222e6f7025f9a36087dd4e MD5 1 10259/12015 oai:riubu.ubu.es:10259/12015 2026-09-08 02:05:21.041 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
