N-부틸렌 화학적 특성, 용도, 생산

화학적 성질
A colorless liquefied petroleum gas. Soluble in most organic solvents; insoluble in water.
용도
Polymer and alkylate gasoline; polybutenes; butadiene; intermediate for C 4 and C 5 aldehy- des, alcohols, and other derivatives; production of maleic anhydride by catalytic oxidation.
일반 설명
An easily liquefied colorless gas boiling from 20.7 to 38°F. Insoluble in water. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Any leak can be either liquid or vapor. Can asphyxiate by the displacement of air. Under prolonged exposure to intense heat containers may rupture violently and rocket.
공기와 물의 반응
Highly flammable. Insoluble in water.
반응 프로필
butene may react vigorously with strong oxidizing agents. Easily ignited and burns well in air. Reacts exothermically with reducing agents to release gaseous hydrogen.
위험도
Asphyxiant gas. Highly flammable, flammable limits in air 1.6–9.3% by volume. Dan- gerous fire and explosion risk.
건강위험
May act as an asphyxiant or slight anesthetic at high vapor concentrations. Vapor concentrations are not usually a hazard at room temperature except in enclosed spaces.
화재위험
Behavior in Fire: Containers may explode in fire. Vapor is heavier than air and may travel long distance to a source of ignition and flash back.
Safety Profile
A simple asphyxlant. Very dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, stop flow of gas. Moderately explosive when exposed to flame. Mxtures with aluminum tetrahydroborate explode after an induction period. When heated to decomposition it emits acrid smoke and fumes.
