Density, Speed of Sound, Isentropic Compressibility, and Excess Volume of Binary Mixtures of 1-propanol or 1-butanol with N-methylcyclohexylamine from (298.15 to 318.15) K

Density and speed of sound for binary mixtures 1-propanol and 1-butanol whit NMethylcyclohexylamineat (298.15, 308.15 and 318.15) K and dry air at atmospheric pressurewere measured simultaneously by an Anton Paar DSA 5000 model high precision vibrating tubedigital densitometer and sound velocity measuring device, with automatic viscosity corrections.The experimental values were used to calculate the isentropic compressibility, excess molarvolumes, and isentropic compressibility deviations [1]. The excess molar volumes for the two Nmethylcyclohexylaminesystems involving 1-propanol and 1-butanol are negative and thissuggest the formation of hydrogen-bonds between molecules involved in the blend [2].
