| 화재 가능성 | Dangerous, when exposed to heat or flameInduced decomposition of the endothermic hydrocarbon leads to flame propagation in absence of air above minimum pressures of 3.4 and 2.1 bar at 20 and 120 °C, respectively.The gas is heavier than air and may travel along the grounddistant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. |

용도
용도
Propyne is produced by thermal or catalytic pyrolysis of propene. Like acetylene, propyne is used as a welding torch fuel, as a specialty fuel, and chemical intermediate.
일반 설명
A colorless liquefied gas with a sweet odor. Mp: -104°C, bp: -23.1°C. Insoluble in water, soluble in ethanol, chloroform and benzene. Moderately toxic by inhalation. Used as a speciality fuel. Denser than air. Vapors may ignite at distant sources of ignition and flash back.
