Here's a professional English summary of the main applications of n-Heptane:
Primary Uses of n-Heptane
1. Fuel & Petroleum Industry
Octane Rating Standard:
Serves as the 0-octane reference fuel (vs. isooctane at 100) for testing gasoline combustion performance.
Solvent for Hydrocarbon Analysis:
Used to determine aromatic content in fuels via ASTM D1319 (FIA method).
2. Industrial Solvents
Adhesives & Coatings:
Key component in rubber cement, tire repair compounds, and specialty paint formulations.
Cleaning Agent:
Degreasing solvent for precision machinery and electronic components.
3. Laboratory Applications
Chromatography:
GC/HPLC mobile phase and reference standard (≥99.9% purity).
ASTM D2268 for distillation analysis of petroleum products.
Spectroscopy:
UV/IR spectroscopy solvent for non-polar samples.
4. Chemical Synthesis
Feedstock:
Intermediate in producing plasticizers (e.g., di-heptyl phthalate) and organic peroxides.
Reaction Medium:
Inert solvent for free-radical polymerizations.
5. Specialty Uses
Pesticide Formulations:
Carrier solvent for agricultural chemicals.
Pharmaceuticals:
Extraction solvent for alkaloids and lipids (GMP grade required).
Key Properties Enabling These Uses
| Property | Relevance |
|---|---|
| Low polarity | Ideal for dissolving non-polar compounds |
| Volatility (BP 98°C) | Easy post-process removal |
| High purity availability | Critical for analytical standards |
Note: Handling requires strict flammability controls (flash point: -1°C).
