"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."
"A database containing solubilities originally published in the IUPAC (International Union for Pure and Applied Chemistry) - NIST Solubility Data Series is now available online."
"The NIST Chemical Kinetics Database includes essentially all reported kinetics results for thermal gas-phase chemical reactions. The database is designed to be searched for kinetics data based on the specific reactants involved, for reactions resulting in specified products, for all the reactions of a particular species, or for various combinations of these."
"This site provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data Program."
