This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of the mixture by weight, the boiling point of the component, the boiling point of the mixture and the density of the mixture. The boiling point was reported at a pressure of 760 mm Hg. article, unless otherwise stated. Where the mixture is divided into layers, values are shown for the upper and lower layers.
Data were obtained from Langes 10th edition of the CRC manual of chemistry and physics 44th edition, Unless otherwise specified, see color table code.
A list of 15825 binary and ternary mixtures were collected and published by the American chemical society. In the database of the azeotrope is also available online via the University of Edinburgh.
