Key Chemical Characteristics

Chemically stable saturated alkane under normal storage conditions; only undergoes cracking, dehydrogenation, oxidation and halogenation under high temperature with catalyst.
Highly flammable; complete combustion produces CO₂ and water vapor with low sulfur content for clean emission; incomplete combustion generates toxic carbon monoxide.
Core petrochemical feedstock: dehydrogenation to produce 1-butene & butadiene; isomerization to manufacture isobutane for MTBE gasoline additive; catalytic oxidation to synthesize maleic anhydride, acetic acid and aldehyde intermediates.
Simple asphyxiant: High concentration displaces oxygen in closed spaces and causes suffocation; no chronic systemic toxicity to human body.
Incompatible with strong oxidants (liquid oxygen, chlorine, hydrogen peroxide); heating mixture may trigger violent combustion and explosion.
Liquid n-butane absorbs massive heat during vaporization, leading to severe frostbite upon direct skin contact.

Handling and Storage

Precautions for safe handling

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Fireproof. Cool.Butane in liquid form may be stored both above and below ground. Besides storage in liquefied form under its vapor pressure at normal atmospheric temperatures, refrigerated liquid storage at atmospheric pressure may be used. Such systems are closed and insulated, and the liquid petroleum gas vapor is circulated through pumps and compressors to serve as the refrigerant for the system. Butane may be stored in pits in the earth capped by metal domes and in underground chambers.
