Speed of sound of some aliphatic amines with 2-methoxyethanol mixtures at 298.15 K

The speed of sound of binary mixtures of 2-methoxyethanol with diethylamine, triethylamine, propylamine, dipropylamine, sec-butylamine and tert-butylamine has been measured as a function of composition at 298.15 K. From the experimental data, values of deviations in the speed of sound (Δu) and isentropic (Δκ) compressibility from ideality have been calculated. The results for Δu and Δκ are discussed on the basis of intermolecular interactions between the components of the analysed mixtures.
