Heat of mixing data are important to the design of industrial processes. They can be used in energy balance and phase equilibrium calculations. Being related to the structure and the energy of interaction of the molecules in the pure substances and in the mixtures, heat of mixing data are of paramount importance also from the theoretical point of view. This subvolume containes selected data on heats of mixing (excess enthalpies) of binary liquid mixtures of organic and inorganic nonelectrolytes, including aqueous-organic systems, in broad ranges of temperature, pressure, and composition. All the data are extracted from the original literature published from 1957 to 2003. The names of the authors, the titles of the publications, and the exact references are given. Estimated uncertainties are reported. The printed volume presents tables for 800 representative mixtures. The CD-ROM displays all these data, as well as 2853 additional data files, in PDF format and in a fully documented computer readable standard electronic file (SELF) format. Moreover, the ELBT-program allows the fast search of data according to property type, chemical system (substances and mixtures), author(s), source and year of publication. Moreover it allows the correlation of the numerical data with several equations and the display of the original data and of the correlated data in tabular and graphical form.
