1-BUTENE Usage And Synthesis
Description1-Butene is a colourless, stable but polymerises exothermically, extremely flammable liquefied gas with an aromatic odour. It is insoluble in water and is one of the isomers of butane. 1-Butene readily forms explosive mixtures with air. It is incompatible with strong oxidising agents, halogens, halogen acids, metal salts, boron trifluoride, fluorine, and nitrogen oxides. 1-Butene of high purity is made by cracking naphtha and separating it from other products by an extra-high-purity distillation column. It is an important organic compound in the production of several industrial materials – for instance, linear low-density polyethylene (LLDPE), a more flexible and resilient polyethylene, and a range of polypropylene resins – and in the production of polybutene, butylene oxide, and the C4 solvents secondary butyl alcohol (SBA) and MEK. The vapour of 1-butene is heavier than air and may travel long distances to an ignition source and flash back.
Chemical Properties1-Butene is a colorless, extremely flammable liquefi ed gas with an aromatic odor. It is insol uble in water and is an isomer of butane. It is highly flammable and readily forms explo sive mixtures with air. 1-Butene of high purity is made by cracking naphtha and separating it from other products by an extra-high purity distillation column. However, 1-butene is incompatible with metal salts, fl uorine, nitrogen oxides, boron trifl uoride, halogen acids, halogens, and strong oxidizing agents. It is an important organic compound in the produc tion of several industrial materials, i.e., linear low density polyethylene (LLDPE), a more fl exible and resilient polyethylene, a range of polypropylene resins, and in the production of polybutene, butylene oxide and in the C4 solvents, secondary butyl alcohol (SBA) and methyl ethyl ketone (MEK). The vapor of 1-butene is heavier than air and may travel long distances to an ignition source and fl ash back.
DefinitionChEBI: A butene with unsaturation at position 1.
General DescriptionColorless gas.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileThe unsaturated aliphatic hydrocarbons, such as 1-BUTENE, are generally much more reactive than the alkanes. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. In the presence of various catalysts (such as acids) or initiators, compounds in this class can undergo very exothermic addition polymerization reactions. May react with oxidizing materials. Aluminum borohydride reacts with alkenes and in the presence of oxygen, combustion is initiated even in the absence of moisture.
Health HazardExposures to 1-butene cause the effects of an asphyxiant and/or an anesthetic (at high concentrations). Workers exposed to 1-butene develop eye irritation.
Fire Hazard1-BUTENE is flammable. Vapor is heavier than air and may travel long distances to an ignition source and flash back.
PrecautionsWhen working with 1-butene, occupational workers should wear proper protectives, preferably a NIOSH-approved full-face positive pressure supplied-air respirator or a self contained breathing apparatus (SCBA). Workers should not wear contact lenses.
