n-Heptane

Name: n-Heptane
SKU: 0

n-Heptane, with the chemical formula C₇H₁₆, is a straight-chain alkane solvent. It appears as a colorless transparent liquid with a mild, petroleum-like odor. It is a component of gasoline but is more notably defined as the primary reference standard for 0 octane rating in fuel testing. n-Heptane exhibits good solvency properties and is widely used in the rubber, adhesive industries, as well as a chemical reagent and organic synthesis intermediate.

Safety Precautions

Health Hazards:
· Irritating to eyes and respiratory tract
· Inhalation of high concentration vapor may cause CNS depression symptoms like dizziness, headache, nausea
· Skin contact may cause dryness, defatting and dermatitis
· Long-term exposure may affect the nervous system
Handling Protection:
· Must be handled in well-ventilated area
· Wear chemical safety goggles, impermeable gloves and protective clothing
· Use explosion-proof equipment and tools
· Avoid contact with skin and eyes
· Do not eat or smoke in work area
Storage & Transportation:
· Store in cool, well-ventilated, explosion-proof area
· Keep containers tightly closed, away from heat and ignition sources
· Use explosion-proof electrical equipment and anti-static devices
· Store separately from oxidizers
· Containers must be properly grounded to prevent static accumulation
Fire Fighting:
· Highly flammable liquid, flash point -4°C, extremely flammable
· Vapor forms explosive mixture with air, explosion limits 1.1-6.7%
· Use foam, dry powder or CO2 to extinguish fire
· Water may be ineffective but can be used to cool exposed containers
· Firefighters must wear self-contained breathing apparatus
