Application of Genetic Programming in Predicting Infinite Dilution Activity Coefficients of Organic Compounds in Water
In this paper, we calculated 37 structural descriptors of 174 organic compounds. The 154 molecules were used to derive quantitative structure infinite dilution activity coefficient relationship by genetic programming, the other 20 compounds were used to test the model. The result showed that molecular partition property and three-dimensional structural descriptors have significant influence o...
متن کاملEstimation of Infinite Dilution Activity Coefficients of Organic Compounds in Water with Neural Classifiers
A new approach is presented for the development of quantitative structure–property relations (QSPR) based on the extraction of relevant molecular features with self-organizing maps and the use of a modified fuzzy-ARTMAP classifier for variable prediction. The present methodology is demonstrated for the development of a QSPR for the aqueous-phase infinite dilution activity coefficient , based on...
متن کاملPredicting infinite dilution activity coefficients of organic compounds in water by quantum-connectivity descriptors
Quantitative structure-property relationship (QSPR) models are developed to predict the logarithm of infinite dilution activity coefficient of hydrocarbons, oxygen containing organic compounds and halogenated hydrocarbons in water at 298.15 K. The description of the molecular structure in terms of quantum-connectivity descriptors allows to obtain more simple QSPR models because of the quantum-c...
متن کاملMeasurements of activity coefficients at infinite dilution of organic solutes and water on polar imidazolium-based ionic liquids
The activity coefficients at infinite dilution, c13, of 55 organic solutes and water in three ionic liquids with the common cation 1-butyl-3-methylimidazolium and the polar anions Cl , [CH3SO3] and [(CH3)2PO4] , were determined by (gas + liquid) chromatography at four temperatures in the range (358.15 to 388.15) K for alcohols and water, and T = (398.15 to 428.15) K for the other organic solute...
متن کاملdesign and construction of a new ebulliometer for measurement of infinite dilution activity coefficients
infinite dilution activity coefficients have been measured for seven binary systems at three different pressures using a newly - designed ebulliometer. the results obtained through these experimental measurements have been compared to literature values for four of the seven binary systems and the calculated deviation has been less than five percent in most cases. having verified the soundness a...
