Abstract

Methanol and ethanol are two useful solvents in various analytical processes, including extraction and separation sciences. Because of the importance of ethanol and methanol's solubility/miscibility, this work has reported interesting descriptive results on the effects of topology, polarization, molecular mass and volume of the solvents and their electronegativity in miscibility of them with methanol and ethanol. Good models were obtained with good performance in training set, test set, cross validation and y-scrambling. The correlation coefficients of leave many out cross validation and test set were above 0.92 in the methanol's model and these values for the ethanol model were 0.93 and 0.85 respectively which showed stability and prediction ability of both suggested QSPR models. Different training and test sets were selected to indicate the stability of results and no dependency on the composition of training/test sets.
