Gas chromatographic method has been used to measure the limiting activity c
oefficient of some aliphatic alcohols (ethanol, 1-propanol, 1-butanol and 1
-pentanol), aromatic hydrocarbons (benzene, toluene, ethylbenzene, o-xylene
and p-xylene), ketones (acetone and methylisobutylketone), ethylacetate an
d chlorobenzene in tetrahydroxyethylethylenediamine (THEEDA) and tetraethyl
pentamine (TEPA). The measurements involving THEEDA have been used to deriv
e UNIFAC group interaction parameters for seven new pairs, while ten pairs
of new group interaction parameters have been derived from the measurements
on TEPA. (C) 1999 Elsevier Science S.A. All rights reserved.
