BUTANE Chemical Properties,Usage,Production

Chemical Properties
colourless gas
General Description
N-BUTANE is a colorless gas with a faint petroleum-like odor. For transportation N-BUTANE may be stenched. N-BUTANE is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. N-BUTANE is easily ignited. Its vapors are heavier than air. Any leak can be either liquid or vapor. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. N-BUTANE is used as a fuel, an aerosol propellant, in cigarette lighters, and to make other chemicals.
Air & Water Reactions
Highly flammable.
Reactivity Profile
N-BUTANE can explode when exposed to flame or when mixed with (nickel carbonyl + oxygen). N-BUTANE can also react with oxidizers. Strong acids and alkalis should be avoided. .
Health Hazard
High exposure produces drowsiness but no other evidence of systemic effect.
Fire Hazard
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
