Abraham model correlations for estimating solute transfer of neutral molecules into anhydrous acetic acid from water and from the gas phase

Abstract

Experimental infinite dilution activity coefficient data, gas-to-liquid partition coefficient data, and solubility data have been combined from the published literature for neutral organic molecules and inert gases dissolved in anhydrous acetic acid. The compiled experimental data were transformed into molar solubility ratios, water-to-acetic acid (P) and gas-to-acetic acid (K) using standard thermodynamic relationships. The derived Abraham model correlations described the observed solubility and partition coefficient data of neutral organic compounds to within 0.18 log units (or less). Our analysis further showed that acetic acid solvent has considerable hydrogen-bond acidity, in agreement with the proposed linear structure for the solvent, and in terms of solubility related properties is not an unusual solvent at all.

Development of Abraham model correlations for solute transfer into both 2-propoxyethanol and 2-isopropoxyethanol at 298.15 K

“…Specific solvents studied in the past five years include diisopropyl ether [8], 2hexadecene [9,10], 1,9-decadiene [9,10], benzonitrile [2], 2-methoxyethanol [11], 2ethoxyethanol [12], 2-butoxyethanol [13], 1,2-propylene glycol [14], acetophenone [15], aniline [15] and acetic acid [16]. All of the solvents listed above contain a single type of functional group attached to either an alkyl chain or aromatic benzene ring, except for the three 2alkoxyalcohols.…”

“…Abraham model correlations have been reported for well over 100 total different tradition organic solvents [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] and IL organic solvents, [47][48][49][50][51][52][53][54][55][56][57][58][59][60][61] as well as for binary aqueous-ethanol [62] mixtures. Our focus in the present study is IL solvents.…”
