methylbenzene
Definition
Noun: 1. A colorless, flammable, aromatic hydrocarbon liquid: Methylbenzene is a volatile organic compound with the chemical formula C₆H₅CH₃. It is a common industrial solvent and a precursor in chemical synthesis. 2. A solvent and chemical feedstock: It is widely used to dissolve other substances, such as paints, rubber, and adhesives, and is a starting material for producing other chemicals, including benzene, xylene, and toluene diisocyanate (used in polyurethane production).
Usage Examples
- Noun:
- The laboratory used methylbenzene to dissolve the organic compound for analysis.
- Proper ventilation is essential when handling methylbenzene due to its flammable vapors.
- This high-octane fuel additive contains a small percentage of methylbenzene.
Advanced Usage
- In chemical nomenclature: "Methylbenzene" is the systematic IUPAC name for the compound more commonly known as "toluene." The name specifies a benzene ring with a single methyl group (-CH₃) substituent.
- In industrial contexts: The term is often used in technical data sheets and scientific literature to specify the pure compound, distinguishing it from commercial mixtures or derivatives.
Variants and Related Words
- Toluene (n): The most common synonym for methylbenzene, frequently used in industrial and commercial settings.
- Phenylmethane (n): An alternative, less common systematic name for the same compound.
- Toluol (n): An archaic term for toluene/methylbenzene, sometimes still found in older technical documents.
Synonyms
- Toluene: The standard common name.
- Solvent naphtha (in some contexts): May refer to a mixture containing methylbenzene/toluene.
Related Phrases and Compounds
- Methylbenzene derivative (n): Any compound chemically derived from methylbenzene, such as nitrotoluene or benzyl alcohol.
- Toluene diisocyanate (TDI) (n): An important industrial chemical produced from methylbenzene, used primarily to make polyurethane foam.
Noun
-
a colorless flammable liquid obtained from petroleum or coal tar; used as a solvent for gums and lacquers and in high-octane fuels
