Infinite dilution activity coefficients and gas-to-liquid partition coefficients of organic solutes dissolved in 1-sec-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and in 1-tert-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide

TL;DR: Inverse gas chromatography was used to measure infinite dilution activity coefficients and gas-to-liquid partition coefficients for 48 organic solute probes in either 1-sec-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide or 1-tert -butyl 3methyloride-3methylamidazolate bis (triffluoromethemide) in the temperature range from 323.15 to 373.15 K as mentioned in this paper.
Journal ArticleDOI

Abraham model correlations for describing the thermodynamic properties of solute transfer into pentyl acetate based on headspace chromatographic and solubility measurements

TL;DR: In this paper, infinite dilution activity coefficients were measured for 32 liquid organic solutes dissolved in pentyl acetate at 298.15 K. Results of the experimental measurements were used to derive Abraham model correlations for describing thermodynamic properties of solute transfer into pentylacetate.
Journal ArticleDOI

Determination of Abraham model solute descriptors for monomeric 3,4,5-trimethoxybenzoic acid from experimental solubility data in organic solvents measured at 298.2 K

TL;DR: In this article, spectroscopic methods were employed to determine the experimental solubility of 3,4,5-trimethoxybenzoic acid dissolved in propylene carbonate, in 19 alcohol, in 4 alkyls ether, in 5 alkyl alkanoate and in 4 alkoxyalcohol solvents at 298.2
Journal ArticleDOI

Determination of Abraham Model Correlations for Solute Transfer into Propyl Acetate Based on Experimental Activity Coefficient and Solubility Data

TL;DR: This paper derived Abraham model correlations for describing solute transfer into propyl acetate to within 0.11 log 10 units and demonstrated that boscalid would show significant partitioning into the skin and fat tissues in the body, and would exhibit considerable baseline toxicity towards the eight aquatic organisms.
Journal ArticleDOI

Abraham model correlations for describing solute transfer into 4-methyl-2-pentanol from both water and the gas phase

TL;DR: In this paper, Abraham model correlations were derived by combining the measured solubility data determined in the present study with published experimental values taken from previous publications, and fifty experimental data points were used in determining the Abraham model correlation presented in this study.
