| Description
| - The densities of five imidazolium-based ionic liquids (1-butyl-3-methylimidazolium tetrafluoroborate, [C1C4Im][BF4]; 1-butyl-3-methylimidazolium hexafluorophosphate, [C1C4Im][PF6]; 1-butyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [C1C4Im][NTf2]; 1-ethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [C1C2Im][NTf2]; 1-ethyl-3-methylimidazolium ethylsulfate, [C1C2Im][EtSO4]) were measured as a function of temperature (from 293 to 415 K) and over an extended pressure range (from 0.1 to 40 MPa) using a vibrating-tube densimeter. The knowledge of the variation of the density with temperature and pressure allows to access to the mechanical coefficients : thermal expansion coefficient and isothermal compressibility. The effects of the anion and of the length of the alkyl chain on the imidazolim ring on the volumetric properties were particularly examined. The mechanical coefficients were compared with those of usual organic solvents, water and liquid NaCl. Finally, a prevision model

- Pomocí vibračního hustoměru byly změřeny hustoty jako funkce teploty (od 293 do 415 K) v tlakovém rozsahu (od 0,1 to 40 MPa) pro pět iontových kapalin založených na imidazolu (1-butyl-3-methylimidazolium tetrafluoroborát, [C1C4Im][BF4]; 1-butyl-3-methylimidazolium hexafluorofosfát, [C1C4Im][PF6]; 1-butyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imid, [C1C4Im][NTf2]; 1-ethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}imid, [C1C2Im][NTf2]; 1-ethyl-3-methylimidazolium ethylsulfát, [C1C2Im][EtSO4]). Znalost změn hustoty s teplotou a tlakem umožňuje získat hodnoty mechanických koeficientů : koeficient tepelné roztažnosti and isotermické stlačitelnosti. Částečně byl vyhodnocen vliv aniontu a délky alkylového řetězce na imidazoliovém kruhu. Mechanické koeficienty iontových kapalin byly porovnány s koeficienty běžných organických rozpouštědel, vody a kapalného NaCl. Byl navržen model založený na %22ideálním%22 chování iontových kapalin. Model dovoluje výpočet molárního objemu iontových k (cs)
