Abstract	U ovom radu sintetizirana je ionska tekućina 1-metilimidazolijev acetat, MimAc, reakcijom 1- metilimidazoliuma i octene kiseline. Potom su mjerene gustoće otopina MimAc u vodi, DMSO, DMA i DMF pri različitim molalitetima i temperaturama. Iz dobivenih gustoća, izračunata su razna volumetrijska svojstva: prividni molarni volumen, parcijalni molarni volumen otapala, parcijalni molarni volumen MimAc, granični prividni molarni volumen, granična prividna molarna ekspanzibilnost i Hepplerov koeficijent. Valjanost Massonove jednadžbe je provjerena te je utvrđena linerana ovisnost prividnog molarnog volumena o koncentraciji pri svim radnim temperaturama. Iz te su ovisnosti određeni veoma važni volumetrijski parametri: granični prividni molarni volumen i Massonov interakcijski koeficijent. Konačno, raspravljena su svojstva promoviranja strukture s pozitivnim koeficijentom (eng. „structure-maker“) ili rušenja strukture s negativnim koeficijentom (eng. „structure-breaker“) ispitivane ionske tekućine u raznim otapalima. Prema vrijednostima Hepplerovog koeficijenta, MimAc u DMF, DMA i DMSO se može opisati kao „structure-breaker“, a u vodi kao granični s koeficijentom blizu nule (eng. „borderline“).
Abstract (english)	Ionic liquid, MimAc was obtained in our laboratory from 1-methylimidazole and acetic acid. The densities of the solutions of MimAc in water, DMSO, DMA and DMF were measured at different molalities and temperatures. The obtained density data calculates volumetric properties (apparent molar volume, standard partial molar volumes, apparent molar volume at infinite dilution, limiting apparent molar expansibilities and Heppler's coefficient). The validity of Masson's equation was checked and applied to describe the evident molar volume dependence on molarity. The apparent molar volume at infinite dilution and interaction coefficient were obtained from this dependence at each temperature. Finally, structure-maker or structure-breaker properties of investigated IL in various solvents are discussed. According to the values of Heppler’s coefficients, MimAc IL, in DMF, DMA, and DMSO could be described as structure-breakers. Values of the Heppler’s coefficient for MimAc in water medium is around zero, so this investigated IL is classified as the borderline.
