What Is Toluene
Toluene is a common ingredient in degreasers. It is a colorless liquid with a sweet smell and taste, and it evaporates quickly. Toluene is found naturally in crude oil, and it is used in oil refining and the manufacturing of paints, lacquers, explosives and glues. The aromatic structure gives it strong solvency for resins and polymers, and its moderate evaporation rate makes it useful in coating formulations.
Use in the Paint and Coatings Industry
Toluene is used in the manufacturing of paints, lacquers and glues, where its strong solvency dissolves the resin systems and its evaporation rate suits the application. In homes, toluene solvent may be found in paint thinners, paintbrush cleaners, nail polish, glues, inks and stain removers. The paint industry is one of the largest consumers of toluene.
Use in the Chemical Industry
Toluene is used in oil refining and as a raw material for the production of benzene, urethane raw materials and other organic chemicals. It is converted to benzene by hydrodealkylation, and it is a feedstock for toluene diisocyanate, which is used in polyurethane production. Toluene derivatives include benzoic acid, benzaldehyde and various aromatic solvents.
Use as a Gasoline Component
A large share of toluene production is used as a component of gasoline, where it raises the octane rating of the fuel pool. The high octane number of the aromatic ring makes toluene an effective antiknock component, and it is blended into the gasoline in proportion to the regulatory limits on aromatics.
Consumer and Environmental Exposure
Toluene is also found in car exhaust and the smoke from cigarettes, because it is a natural component of crude oil and is formed during combustion. The consumer products that contain toluene are used under ventilation, and the exposure limits are set by the occupational safety regulations for the workplaces that handle the solvent.
