Isentropic Compressibilities of Butylamine+n-Alkane at 303.15 and 313.15 K

Abstract

Isentropic compressibilities of binary mixtures of butylamine + hexane, butylamine + heptane, and butylamine + octane were determined at 303.15 and 313.15 K. The three mixtures exhibit positive deviations in compressibility. This is ascribed to a structure-breaking effect of n-alkanes. The deviation becomes more positive with increase in chain length of n-alkanes and with increase in temperature.
