High Quality Content by WIKIPEDIA articles! This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. Data includes composition of mixture by weight (in binary azeotropes when only one fraction is given, it is the fraction of the second component), boiling point (b.p.) of components, boiling point of mixture, and specific gravity of mixture. Boiling points are at 760 mm Hg unless otherwise stated. Where the mixture separates into layers, values are shown for upper (U) and lower (L) layers.
