Following its refinement, LPG is stored and distributed as a liquid under pressure until used, at which point it is utilised as either a liquid or a gas (vapour). REACH Propene . Residential propane tank regulations and propane tank distance requirements are important for a safe installation. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst. Propane is generally stored, as a liquid, in steel vessels ranging from small BBQ gas bottles to larger gas cylinders and storage tanks. Propane is a flammable hydrocarbon gas that is liquefied through pressurisation and commonly used for fuel in heating, cooking, hot water and vehicles. Propane is also used as fuel for internal combustion engine applications. Polypropylene, or 'polypro', has been used for the fabrication of cold-weather base layers, such as long-sleeve shirts or long underwear. La principale caractéristique du propène est la réactivité de la double liaison qui en fait un bon réactif pour des réactions de polymérisation, d'addition et d'oxydation. Propane is explosive under the right circumstances. Propane is LPG but not all LPG is propane. Propene is also used to produce isopropanol, acrylonitrile and propylene oxide. 5th ed.Vol A1: Deerfield Beach, FL: VCH Publishers, 1985 to Present., p. VA1 141 .
