2-Butyne Chemical Properties,Uses,Production

Chemical Properties

clear colorless to light yellow liquid

Uses

2-Butyne is used to synthesize alkylated hydroquinones in the total synthesis of Vitamin E. It is also used as pharmaceutical intermediates.

General Description

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 Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

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.

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.]
