benzine
Noun 1. A volatile, flammable liquid mixture of hydrocarbons: Benzine is a colorless, highly flammable liquid derived from petroleum, primarily used as a solvent or fuel. It is a mixture, not a pure compound, and is sometimes called petroleum ether or ligroin. It is distinct from benzene, which is a specific aromatic compound. 2. A solvent for cleaning or extraction: In industrial and laboratory contexts, benzine refers to a solvent fraction used to dissolve oils, fats, and greases, often for cleaning or in chemical processes.
- The old mechanic used benzine to clean the greasy engine parts.
- This adhesive should be thinned with a solvent like benzine.
- Benzine is highly volatile, so it must be stored away from any ignition sources.
- In the early 20th century, benzine was a common spot remover for clothing.
- Technical Specification: In technical parlance, "benzine" often refers to specific boiling point fractions of petroleum, such as petroleum ether (a low-boiling mixture) or ligroin (a higher-boiling mixture). Its composition can vary.
- Historical Context: The term "benzine" was used more commonly in the past. In modern English, more specific terms like "petroleum ether," "ligroin," or "naphtha" are often preferred to avoid confusion with "benzene."
- Benzene (noun): A specific, pure aromatic hydrocarbon (C₆H₆) with a ring structure. It is a known carcinogen and is chemically distinct from the mixture called benzine.
- Petroleum Ether (noun): A common synonym for a light, volatile form of benzine.
- Ligroin (noun): A synonym for a petroleum fraction similar to benzine, often with a slightly higher boiling range.
- Naphtha (noun): A broader term for various volatile petroleum fractions, which can include materials similar to benzine.
- Petroleum ether
- Ligroin
- Petroleum spirit
- (In some contexts) Naphtha
CRITICAL DISTINCTION: The words "benzine" and benzene are often confused. While "benzine" is a flammable solvent mixture, "benzene" is a specific, pure, and highly toxic aromatic compound. Using the correct term is essential for safety and accuracy in scientific, industrial, and regulatory contexts.
- a colorless liquid hydrocarbon; highly inflammable; carcinogenic; the simplest of the aromatic compounds
