Acoustic, viscometric and volumetric properties of binary mixtures of N-methylacetamide with some aliphatic mono and di alkyl amines at T=308.15 K

Excess molar volume, deviation in viscosity, and deviation in isentropic compressibility for the binary mixtures of amines with N-methylacetamide have been calculated from density, viscosity and speed of sound measurements at T = 308.15 K. The amines chosen for the study are diethyl amine, n-propyl amine, diisopropyl amine, n-butyl amine and di-n-butyl amine. All the properties have been fitted to the Redlich–Kister polynomial using multiparametric non-linear regression analysis to estimate the binary coefficients and standard errors. The results of excess properties have been discussed in terms of molecular interactions.
