| ISOBUTANE Usage And Synthesis |
| Chemical Properties | colourless odourless gas (or colourless cryogenic liquid) |
| General Description | ISOBUTANE is a colorless gas with a faint petroleum-like odor. ISOBUTANE is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. ISOBUTANE is easily ignited. The vapors are heavier than air. Any leak can either be liquid or vapor. ISOBUTANE can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. |
| Air & Water Reactions | Highly flammable. |
| Reactivity Profile | ISOBUTANE is incompatible with the following: Strong oxidizers (e.g., nitrates & perchlorates), chlorine, fluorine, (nickel carbonyl + oxygen) . |
| Health Hazard | Central nervous system depression ranging from dizziness and incoordination to anesthesia and respiratory arrest, depending on concentration and extent of inhalation. Irregular heartbeat is rare but is a dangerous complication at anesthetic levels. |
| 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. |
