Ionic liquids are considered environmentally friendly media for various industrial applications. Basic data on physicochemical properties are significant for a new material, in terms of developing its potential applications. In this work, 1-ethyl-3-methylimidazolium fluoride ([EMIm]F) ionic liquid was synthesized via an anion metathesis process. Physical properties including the density, viscosity, electrical conductivity, and thermal stability of the product were measured. The results show that the density of [EMIm]F decreases linearly with temperature increases, while dynamic viscosity decreases rapidly below 320 K and the temperature dependence of electrical conductivity is in accordance with the VFT (Vogel-Fulcher-Tammann) equation. The temperature dependence of the density, conductivity, and viscosity of [EMIm] F can be expressed via the following equations: rho = 1.516 - 1.22 x 10(-3) T, sigma(m) = 4417.1exp[953.17/(T - 166.65)] and eta = 2.07 x 10(-7)exp(-5.39 x 10(4)/T), respectively. [EMIm]F exhibited no clear melting point. However, its glass transition point and decomposition temperature are -71.3 degrees C and 135 degrees C, respectively.
