Understanding Toluene
Toluene, also known as methylbenzene, is an aromatic hydrocarbon with the molecular formula C₇H₈. It is a colorless, volatile liquid that emits a sweet smell, making it recognizable in many industrial environments. Toluene is derived from benzene and is often found in products like paint thinners, adhesives, and coatings.
Chemical Properties of Toluene
Toluene has a molecular weight of 92.14 g/mol and a CAS number of 108-88-3. It is insoluble in water but soluble in organic solvents, which enhances its utility in various chemical processes. Its ability to dissolve numerous inorganic and organic materials makes it a preferred choice in laboratories and industrial settings.
Types of Toluene
Different grades of toluene are available based on purity and intended use:
- ACS Reagent Grade: Known for its high purity, it is suitable for chemical analysis and research (www.sciencecompany.com).
- Industrial Grade: This grade is used widely as a solvent for various applications, including paints and adhesives (corecheminc.com).
- Laboratory Grade: Often utilized in research and quality control, this grade maintains a balance between purity and cost (www.laballey.com).
- HPLC Grade: Designed for high-performance liquid chromatography, this grade offers ultra-high purity (www.mcmaster.com).
