butane

 [bu´tān]
an aliphatic hydrocarbon, C4H10, from petroleum; used in pharmacy as an aerosol propellant.

bu·tane

(byū'tān),
C4H10; a gaseous hydrocarbon present in natural gas; two isomers are known, both of which are anesthetically active: N-butane is CH3(CH2)2CH3 and isobutane is CH3CH(CH3)CH3 (or 2-methylpropane).

butane

A linear (unbranched) alkane hydrocarbon which is a flammable gas at room temperature (boiling point, 0ºC/30–34ºF).
 
Uses
Lighter fluid, refrigerant.

Adverse effects
Euphoria, drowsiness, narcosis, arrhythmias, memory loss, frostbite, death due to asphyxiation and ventricular fibrillation.

''We knew isobutane had a high rate of efficiency as cooling medium,'' said Shinji Hirai, chief specialist in Toshiba's Refrigerator Engineering Department.
Isobutane's refrigeration power is 1.8 times that of HFC but at that rate of cooling capacity, the pressure is as low as about one third of that of propane gas when a ''leakage'' in one case in a million is taken into consideration.
And Neste Oy in Finland has developed a "supercritical slurry-in-loop" process using propane as the diluent instead of isobutane. Neste's process, still in the pilot stage, works like a conventional liquid slurry, but is really a gas compressed to a liquid at high pressure.
Nucleators are recommended for direct-gas applications in PS, polyolefins, ABS, PPO, PPE, using fluorocarbons, pentane, butane, isobutane, nitrogen, and carbon dioxide.
