1-BUTEN-3-YNE Usage And Synthesis

Description

Vinylacetylene, also known as butenyne, monovinylacetylene, 1-butene-3-yne, 1-butyn- 3-ene, 3-buten-1-yne, buten-3-yne, ethynylethene, 1-butenyne and vinylethyne, is a derivative of acetylene.

Chemical Properties

Vinylacetylene is a gas with a smell similar to acetylene. The melting point is –118 to –120°C, the boiling point is 5.5 °C under atmospheric pressure, and the boiling point of vinylacetylene under different pressures is shown in Table 7.1.

Uses

Vinylacetylene is mainly used for the production of chloroprene, leaf alcohol and methanol adhesives. It is also used for the production of divinyl ether and methyl vinyl (methyl) ketone-based polymer.

Definition

ChEBI: Butenyne is an acyclic acetylene, an acyclic olefin, an enyne and a terminal acetylenic compound.

General Description

A colorless gas or liquid. Derived by the dimerization of acetylene. Used in the synthesis of neoprene and for other organic syntheses.

Air & Water Reactions

Highly flammable. Oxidizes in air to form unstable peroxides that may explode spontaneously.

Reactivity Profile

1-BUTEN-3-YNE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. Forms an explosive salt with silver nitrate. Thermally unstable, under pressure, in combination with 1,3-butadiene [Loss Prev., 1971, 5, 67].

Synthesis

Acetylene is dimerized in the presence of hydrochloric acid solution of cuprous chloride and ammonium chloride to obtain vinylacetylene.
