The densities and sound velocities of binary mixtures of triethylene glycol are measured at different temperatures and at frequency of 2 MHz over entire range of mole fraction. Various theoretical models, such as Nomoto, Impedance, Junjie, Van Dael and Vangeel, have been used to measure theoretical ultrasonic velocities. The average percentage error was estimated and the chi-square fitness test was also used to check the validity of theoretical models. The variance from the experimental results is interpreted in terms of molecular interactions between the components of the binary mixtures.
