2-부틴 C화학적 특성, 용도, 생산
화학적 성질
clear colorless to light yellow liquid용도
2-Butyne is used to synthesize alkylated hydroquinones in the total synthesis of Vitamin E. It is also used as pharmaceutical intermediates.일반 설명
A clear colorless liquid with a petroleum-like odor. Flash point below -4°F. Boiling point 81°F. Less dense than water and insoluble in water. Vapors heavier than air.공기와 물의 반응
Highly flammable. Insoluble in water.반응 프로필
2-Butyne may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.위험도
Flammable, dangerous fire risk. Moderate explosion hazard.건강위험
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.Safety Profile
A simple asphyxiant. Very dangerous fire hazard when exposed to heat or flame; can react with oxidzing materials. Moderately explosive in the form of vapor when exposed to heat or flame. To fight fire, use foam, CO2, dry chemicals. See also ACETYLENE COMPOUNDS and ARGON (for a description of simple asphyxiants).Purification Methods
Stand it over sodium for 24hours, then fractionally distil it under reduced pressure into a cooled receiver. [Beilstein 1 IV 971.]2-부틴 준비 용품 및 원자재
