Description: This presentation is part of the faculty lecture series UNT Speaks Out on Water Conservation. In this presentation, the author discusses sustainable resource management and water conservation, including discussions on the Trinity River and water conservation in North Texas.

Description: This book chapter discusses the prediction of toxicity, sensory responses and biological responses with the Abraham model.

Description: This article discusses the correlation and prediction of solute transfer to chloroalkanes from both water and the gas phase. Data have been compiled from the published literature on the partition coefficients of solutes and vapors into chloroform, carbon tetrachloride, dichloromethane and 1-chlorobutane from both water and from the gas phase. The logarithms of the water-to-chloroalkane (log P) and gas-to-chloroalkane partition coefficients (log K) are correlated with the Abraham solvation parameter model. The derived correlations describe the observed log P and log K values within standard deviations of about 0.13-0.20 log units. For chloroform and carbon tetrachloride, the derived correlations were validated using training set and test set analyses.

Description: This article discusses enthalpy of solvation correlations for gaseous solutes dissolved in chloroform and 1,2-dichloroethane based on the Abraham model. Abstract: Enthalpy of solvation data have been compiled from the published literature for more than 80 solutes dissolved in chloroform and 1,2-dichloromethane. Mathematical correlations based on the Abraham general solvation parameter model are developed for describing the experimental solvation enthalpies to within standard deviations of 2.10 kJ/mol (chloroform) and 1.72 kJ/mol (1,2-dichloroethane). Division of the measured values into a training set and a test set shows that there is no bias in predictions, and that the estimative capability of the correlations is better than 2.5 kJ/mol.

Description: This article discusses the development of correlations for describing solute transfer into acyclic alcohol solvents based on the Abraham model and fragment-specific equation coefficients. Abstract: Gas-to-alcohol partition coefficients have been compiled for 1880 different solute-alcohol combinations, which comprised 23 acyclic alcohols. These partition coefficients were converted into water-to-alcohol partition coefficients using the corresponding gas-to-water partition coefficients. Both sets of partition coefficients were analyzed using the Abraham solvation parameter model with fragment-specific equation coefficients. The derived equations correlated the experimental gas-to-alcohol and water-to-alcohol partition coefficient data to within 0.14 and 0.15 log units, respectively. The fragment-specific equation coefficients that have been calculated for the CH3, CH2, CH, C and OH fragment groups can be combined to yield expressions capable of predicting the partition coefficients of solutes in other anhydrous alcohol solvents.
