Correlation of Azeotropic Data

An Empirical Correlation among Azeotropic Data

“…In the 1940's, Mair et al (1941) and Skolnik (1948) described graphical methods of correlating the composition of the azeotropes within an organic series, which were of limited utility. Meissner and Greenfield (1948) reported another graphical correlation which led to eq 2.…”

Azeotrope Formation between Thiols and Hydrocarbons

“…Such correlations are extremely valuable, because they allow the prediction of unknown data which are often required and for some reason or other are not easily obtainable. This aspect of the vapor-liquid relationships of binary systems has been given much consideration of late and three papers on this subject have appeared within 8 months (11,17,22). All three are concerned with graphical methods of correlation.…”

Solvent Extraction

“…Several papers treating azeotropic mixtures (46,50,68) which may find use in dealing with liquid extraction processes appeared during the year. Correlations of liquid densities and of surface tensions by Othmer and co-workers (54) should ultimately find use in design.…”

“…Tie-line data for systems of ethylene glycol and water with higher alcohols were correlated by previously known methods (48). A series of papers dealing with the theory of nonideal solutions and equilibrium in nonelectrolyte mixtures was presented at the 114th meeting of the American Chemical Society (81,48,56,68).…”
