ISOBUTANE Chemical Properties,Uses,Production

Chemical Properties

colourless odourless gas (or colourless cryogenic liquid)

Definition

ChEBI: An alkane that is propane substituted by a methyl group at position 2.

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.

Purification Methods

Olefins and moisture can be removed by passage at 65o through a bed of silica-alumina catalyst which has previously been evacuated at about 400o. Alternatively, water and CO2 can be removed by passage through P2O5, then asbestos impregnated with NaOH. Treatment with anhydrous AlBr3 at 0o then removes traces of olefins. Inert gases can be separated by freezing the isobutane at -195o and evacuating out the system. [Beilstein 1 IV 282.]
