The IUPAC-NIST Solubility Database contains solubilities originally published in the IUPAC (International Union for Pure and Applied Chemistry) - NIST Solubility Data Series. Mutual solubilities and liquid-liquid equilibria of binary, ternary and quaternary systems are presented. Typical solvents and solutes include water, sea water, heavy water, inorganic compounds, and a variety of organic compounds such as hydrocarbons, halogenated hydrocarbons, alcohols, acids, esters and nitrogen compounds. For many systems, sufficient data were available to allow critical evaluation. Data are expressed as mass and mole fractions as well as the originally reported units. There are over 30,000 solubility measurements, compiled from 11 volumes of the IUPAC Solubility Data Series. There are about 1028 chemical substances in the database and 3,619 systems, of which 338 have been critically evaluated. The database has over 800 references.
