CYCLOBUTANE Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
Cyclobutane is a colorless, flammable, explosive gas.
Vorbereitung Methode
Cyclobutane is produced from cyclobutene and reutilized in catalytic cracking processes.
Definition
ChEBI: Cyclobutane is a cycloalkane and a member of cyclobutanes.
Allgemeine Beschreibung
Gas that condenses to a liquid at 55°F. Density of liquid 0.7 g / cm3. Insoluble in water. Soluble in alcohol, acetone and ether. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
CYCLOBUTANE may be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted material and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.
Brandgefahr
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.
läuterung methode
This easily liquefiable gas is dried over Na at melting ice temperature for 4days and distilled at low temperature through a Podbielniak (p 10) precision still. A dry sample has been prepared by passage through P2O5 and distilled repeatedly until all fractions had similar vapour pressures at 0o.
