Organic molecular solvents - Main physico-chemical constants

In recent years, the situation regarding the use of solvents in industry and laboratories has changed considerably. Strict regulations have been introduced to severely limit the use of solvents that present health and environmental hazards. These precautions in use, which are part of what is generally referred to as green chemistry, have led to the abandonment or severe limitation of a number of solvents which previously featured prominently (chlorinated solvents, CFCs, glycol ethers, aromatic solvents, etc.). Other solvents that are seldom used, or in some cases did not exist in the first place, must now be mentioned (ionic liquids at room temperature, perfluorohydrocarbons, certain esters, etc.). Supercritical fluids (scCO ₂ , scH ₂ O), which are commonly used in certain processes but require special facilities, do not appear in this set, which presents organic molecular solvents in tabular form. It covers 536 compounds and, for each of them, some twenty data including a dozen physico-chemical constants are listed.

Given the very large number of solvents listed, their properties are divided into two folders:

[K 310v2] – Main physico-chemical constants ;

[K 311v2] – Données en solutions et valeurs de risk.

Ionic liquids at room temperature will be the subject of a separate [K 313] file in this database.
