Description
Summary:The refraction, dielectric, viscosity, density, data of the binary mixtures of N , N -dimethylacetamide (DMA) with n -butanol at 308.15 and 313.15 K. The measured parameters used to obtain derived properties like Bruggeman factor, molar refraction and excess static dielectric constant, excess inverse relaxation time, excess molar volume and excess viscosity, excess molar refraction. The variation in magnitude with composition and temperature of these quantities has been used to discuss the type, strength and nature of binary interactions. Results confirm that there are strong hydrogen-bond interactions between unlike molecules of DMA+ n -butanol mixtures and that 1: 1 complexes are formed and strength of intermolecular interaction increases with temperature.
