Chemische Eigenschaften
clear colorless to light yellow liquid
Verwenden
2-Butyne is used to synthesize alkylated hydroquinones in the total synthesis of Vitamin E. It is also used as pharmaceutical intermediates.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
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.
Hazard
Flammable, dangerous fire risk. Moderate
explosion hazard.
Health Hazard
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.
Sicherheitsprofil
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).
läuterung methode
Stand it over sodium for 24hours, then fractionally distil it under reduced pressure into a cooled receiver. [Beilstein 1 IV 971.]
