Abstract:A new whole concentration range binary system of 1 -cyanopropyl -3 -methylimidazolium tet-rafluoroborate ( [ C3 CNmim ] [ BF4 ] ) and acetonitrile ( AN ) was prepared .The thermodynamic properties of density , dynamic viscosity , and electrical conductivity of the binary system were determined over the whole con-centration at 288.15 K, 298.15 K, 308.15 K, and 318.15 K under atmospheric pressure , respectively.The excess molar volume ( VE ) of the binary system was calculated based on densities values and empirical equation , the composition and temperature dependences of the excess molar volume for the binary system were discussed . The temperature dependences of the dynamic viscosity and electrical conductivity for the binary system were graphically depicted by the Vogel -Fulcher-Tamman (VFT) equation.The VFT adjustable parameters were al-so calculated.Finally, internal interactions of the binary system were studied by density functional theory ( DFT) , and the hydrogen bond interactions of binary system were also discussed .
