Three ionic liquids were studied: 1-butylpyridinium bis(trifluoromethyl-sulfonyl)imide, 1-hexylpyridinium bis(trifluoromethylsulfonyl)imide, and 1-hexylpyridinium tetrafluoroborate. The following thermophysical properties were measured: density, speed of sound, refractive index, surface tension, isobaric molar heat capacity, kinematic viscosity, and electrical conductivity. The thermophysical properties at atmospheric pressure were correlated with temperature, noting that the starting temperature for the speed of sound measurements depended on the ionic liquid. From these experimental results, some derived properties (isentropic compressibility, molar refraction, and dynamic viscosity) are calculated. These results together with those published previously for 1-butylpyridinium tetrafluoroborate are discussed. © 2022 American Chemical Society. 000130996 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E31-20R 000130996 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000130996 590__ $$a2.6$$b2022 000130996 591__ $$aTHERMODYNAMICS$$b24 / 63 = 0.381$$c2022$$dQ2$$eT2 000130996 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b103 / 178 = 0.579$$c2022$$dQ3$$eT2 000130996 591__ $$aENGINEERING, CHEMICAL$$b83 / 141 = 0.589$$c2022$$dQ3$$eT2 000130996 592__ $$a0.625$$b2022 000130996 593__ $$aChemistry (miscellaneous)$$c2022$$dQ2 000130996 593__ $$aChemical Engineering (miscellaneous)$$c2022$$dQ2 000130996 594__ $$a5.4$$b2022 000130996 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000130996 700__ $$aPelegrina, Adrián 000130996 700__ $$aSánchez Rubio, Miguel 000130996 700__ $$0(orcid)0000-0001-8790-8211$$aArtigas, Héctor$$uUniversidad de Zaragoza 000130996 700__ $$0(orcid)0000-0003-3632-6822$$aLafuente, Carlos$$uUniversidad de Zaragoza 000130996 7102_ $$12012$$2755$$aUniversidad de Zaragoza$$bDpto.
