Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Most of those methods, but not all, involve the use of a solvent either for liquid-liquid extraction or extractive distillation. Many different solvents are suitable, including sulfolane (C 4 H 8 O 2 S), furfural (C 5 H 4 O 2), tetraethylene glycol (C 8 H 18 O 5), dimethylsulfoxide (C 2 H 6 OS), and N-methyl-2-pyrrolidone (C 5 H 9 NO).
Contact cement, a fast-drying glue, is widely used as an inhalant, as it typically contains solvents such as toluene which vaporize at room temperature. Even though solvent glue is normally a legal product, there is a 1983 case where a court ruled that supplying glue to children is illegal.
Replacing dichloromethane is advantageous when conditions require higher boiling solvents, since trifluorotoluene boils at 103 °C it has a higher boiling point than dichloromethane, which has a boiling point of ~40 °C. As a solvent, trifluorotoluene is useful in mild Lewis-acid catalyzed reactions, such as the Friedel-Crafts preparations.
