This reference compiles published data for the solubility of a variety of organic nonelectrolytes and unionized weak electrolytes in water. It presents about 16,000 solubility records with data for some 4,000 compounds, including pharmaceuticals, pollutants, nutrients, herbicides, pesticides, and agricultural, industrial, and energy- related compounds. These data were extracted from about 1,800 scientific references contained in the AQUASOL dATAbASE. Each compound is identified by a sequential number along with molecular formula, compound name, synonyms, molecular weight, Chemical Abstracts Service Registry Number, melting point, and boiling point. For convenience, all solubility data are converted to moles per liter and grams per liter.
