This volume, written by an authority on hydrocarbon chemistry and liquid-liquid phase relations, lists over 6000 critical solution temperatures (the minimum temperature for mixing of two substances in all proportions as liquids). Also included are about 800 aniline point observations; methods for determining CST; guides to using CST data and to estimating the CST for untested systems. Among uses of CST are: screening possible extraction solvents for selectivity; approximating liquid solubility at any temperature below the CST; characterizing hydrocarbons; analysis of mixtures, especially where water is one component, and providing an insight into molecular structure. CONTENTS Introduction and six Figures.. .Tables: Critical Solution Temperatures . . . Aniline and Furfural Points . . . Lower Critical Solution Temperatures . . . Mutual Miscibility of Liquids (tabulations of numerical CST data from charts in five published compilations).. .Bibliography. 246 pages.
