Technology, Tehran, Iran 3 University of Mazandaran,Babul, Iran Liquid-liquid equilibrium data of the various ternary
systems of water+propionic acid+solvent(s) have been correlated with some
important activity coefficient models containing Wilson, NRTL, and UNIQUAC
models by using the PRO/II computer program. The solvents which have been
considered in this work were methyl butyl ketone, methyl propyl ketone,
isobutyl ketone, isopropyl ketone, methyl ethyl ketone, and 1-buthanol.
Temperature range was between 25-55 ºC. Although all of these activity |
