Contributions of additional group interaction parameters through limiting activity coefficient measurements on aliphatic alcohols, aromatic hydrocarbons, ketones and an ester in organic phosphates

Gas chromatographic technique is used to measure the limiting activity coef ficients of some aliphatic alcohols (ethanol, 1-propanol, 1-butanol, 1-pent anol), aromatic hydrocarbons (benzene, toluene, o-xylene, p-xylene, ethylbe nzene), ketones (acetone, methylisibutylketone), and an ester (ethylacetate ) and chlorobenzene in three organic phosphates (tricresylphosphate, trixyl olphosphate, tributylphosphate). The limiting activity coefficient are used to derive the UNIFAC group interaction parameters for 13 new pairs. (C) 19 99 Elsevier Science S.A. All rights reserved.
