Excess Volumes and Isentropic Compressibilities of Binary Mixtures of an Alcohol and Isobutyl Methyl Ketone

Abstract

Excess volumes and isentropic compressibilities for the binary mixtures of propan-1-ol, butan-1-ol, pentan-1-ol, hexan-1-ol with isobutyl methyl ketone were determined at 303.15 and 313.15 K. Excess volumes of the four mixtures are negative over the whole range of compositions at both the temperatures. Deviations in isentropic compressibility are also negative in all cases, except for propan-1-ol + isobutyl methyl ketone. In this system, the deviation in isentropic compressibility shows an inversion in sign at 303.15 K.
