Excess Volumes and Excess Isentropic Compressibility of Binary Mixtures of N, N-Dimethyl for mamide with n-Alcohols at 303.15 K

Abstract

Abstract Excess volumes and isentropic compressibility's for binary liquid mixtures of N,N-d-dimethyl-formamide with methanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol and 1-heptanol have been measured at 303.15 K. Both the excess properties are negative in the systems with lower alcohols and become positive with increase in alkanet chain length of alcohols. The sign and magnitude of excess functions have been discussed in terms of the combination of the effects due to difference in size, shape and intermolecular interaction between unlike components.
