1-BUTEN-3-YNE Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
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.
Chemische Eigenschaften
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.
Verwenden
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.
Allgemeine Beschreibung
A colorless gas or liquid. Derived by the dimerization of acetylene. Used in the synthesis of neoprene and for other organic syntheses.
Air & Water Reaktionen
Highly flammable. Oxidizes in air to form unstable peroxides that may explode spontaneously.
Reaktivität anzeigen
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].
Synthese
Acetylene is dimerized in the presence of hydrochloric acid solution of cuprous chloride and ammonium chloride to obtain vinylacetylene.
