Industrial Chemical Isobutylene Colourless Gaseous 

Isobutylene (also called 2-methylpropene, isobutene, and γ-butylene because chemists aren’t wonderful at sticking to a one naming system) is a colourless, gaseous hydrocarbon at room temperature. Its flash point is -80 ˚C meaning that above this temperature, if an ignition source is present, isobutylene will ignite. Since the coldest temperature ever recorded on Earth was -89 ˚C, isobutylene is only a spark away from flames nearly everywhere on earth at all times. Isobutylene is widely used in the synthesis of many things, largely because it contains a double bond which can be easily reacted to form other products. It can, for example, react with ethanol to form ethyl tert-butyl ether (ETBE), a gasoline additive that raises the octane number, making the fuel more resistant to knocking, or spontaneous combustion. Or it can be combined with itself in a long chain to form a polymer, butyl rubber. Polymer and chemical grade isobutylene is typically obtained by dehydr…
