Hydrocarbon products are an important class of solvents, but their selection requires comprehensive consideration of solubility, safety, and environmental requirements. In practical applications, it is recommended to prioritize low-toxicity or environmentally friendly solvents and strictly adhere to operating procedures.
Main Application Areas
- Industrial cleaning: Removal of oil and grease (e.g., cleaning of mechanical parts).
- Paints and inks: Used as diluents to adjust viscosity.
- Chemical synthesis: Used as a reaction medium or extractant.
- Daily chemical products: Oil solvents in cosmetics (e.g., makeup remover).
Advantages and Precautions
- Advantages: Strong solvency, rapid evaporation, low cost.
- Precautions:
- Toxicity: Aromatic hydrocarbons such as benzene pose a carcinogenic risk and require protective measures.
- Flammability: Most are highly flammable and require fire and explosion prevention measures.
- Environmental impact: Some are difficult to degrade and require compliant disposal.
Environmental Alternatives Trend
With strengthening environmental regulations, water-based solvents and bio-based solvents (such as limonene) are gradually replacing traditional hydrocarbon solvents.
