| Brandgefahren | Excerpt from ERG Guide 115 [Gases - Flammable (Including Refrigerated Liquids)]: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), Methane (UN1971) and Hydrogen and Methane mixture, compressed (UN2034) 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. CAUTION: When LNG - Liquefied natural gas (UN1972) is released on or near water, product may vaporize explosively.

Anwendungen & Verwendung
Beschreibung
Cyclopropane (molecular formula: C3H6) is a kind of cycloalkane molecule. Cyclopropane and propene are isomers of each other. It can be used as a kind of anaesthetic. However, due to its side effect of causing a sudden decrease in blood pressure and potentially causing cardiac dysrhythmia, it has not been available for clinical use since mid-1980 as more. Its mechanism of action is through acting as the NMDA receptor antagonist as well as inhibiting the AMPA receptor, inhibiting the nicotine acetylcholine receptor, and activates certain K2P channels.
Verwenden
Cyclopropane was initially investigated because it was thought to be the toxic element in ethylene. Instead, it turned out to be an excellent anesthetic with very rapid onset and recovery while maintaining stable hemodynamics. Its use was ultimately limited because it was highly explosive. Cyclopropane is a sweet-smelling, flammable gas that has little or no laboratory, commercial, or industrial use.
