Dilithium acetylide is an organometallic compound with the formula L i2 C 2. It is typically derived by double deprotonation of acetylene. X-ray crystallography confirms the presence of C≡C subunits attached to lithium, resulting in a polymeric structure. [ 3 ]
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 ...
Copper(I) acetylide, Kupfercarbid or cuprous acetylide, is a chemical compound with the formula Cu 2 C 2. 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 is a reddish-brown explosive powder.
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 − ] .
The carbide product produced generally contains around 80% calcium carbide by weight. The carbide is crushed to produce small lumps that can range from a few mm up to 50 mm. The impurities are concentrated in the finer fractions. The CaC 2 content of the product is assayed by measuring the amount of acetylene produced on hydrolysis. As an ...
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]
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.
