It consists of Cu + cations and acetylide anions − C≡C −, with the triple bond between the two carbon atoms. Although never characterized by X-ray crystallography, the material has been claimed at least since 1856. [2] One form is claimed to be a monohydrate with formula Cu 2 C 2 ·H 2 O. Copper(I) acetylide is a reddish-brown explosive ...
In chemistry, an acetylide is a compound that can be viewed as the result of replacing one or both hydrogen atoms of acetylene (ethyne) HC≡CH by metallic or other cations. Calcium carbide is an important industrial compound, which has long been used to produce acetylene for welding and illumination. It is also a major precursor to vinyl ...
Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). [5] This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole [6] and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892:
Barium carbide can be synthesized as an impure compound by reducing barium carbonate powder with metallic magnesium in the presence of carbon. [3] Barium carbide can also be made by reducing carbon dioxide with hot barium metal at 600°C. [4] These methods are used because of their high yield, and because the carbide is used to make acetylene.
Silver acetylide is an inorganic chemical compound with the formula Ag 2 C 2, a metal acetylide. The compound can be regarded as a silver salt of the weak acid , acetylene . The salt's anion consists of two carbon atoms linked by a triple bond , thus, its structure is [Ag + ] 2 [ − C≡C − ] .
Strontium carbide (also more precisely known as strontium acetylide or strontium dicarbide) is a salt with chemical formula SrC 2. It was first synthesized by Moissan in 1894. [1] Strontium carbide can be formed in an electric arc furnace from strontium carbonate and a reductant, such as a reducing sugar [1] [2] or magnesium metal. [3]
Each lithium atom is surrounded by six carbon atoms from 4 different acetylide anions, with two acetylides co-ordinating side -on and the other two end-on. [3] [6] The relatively short C-C distance of 120 pm indicates the presence of a C≡C triple bond. At high temperatures Li 2 C 2 transforms reversibly to a cubic anti-fluorite structure. [7]
