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, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2. Its main use industrially is in the production of acetylene and calcium cyanamide . [ 3 ]
Dilithium acetylide is an organometallic compound with the formula Li 2 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 ]
Calcium carbide. Several carbides are assumed to be salts of the acetylide anion C 2− 2 (also called percarbide, by analogy with peroxide), which has a triple bond between the two carbon atoms. Alkali metals, alkaline earth metals, and lanthanoid metals form acetylides, for example, sodium carbide Na 2 C 2, calcium carbide CaC 2, and LaC 2. [2]
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 − ] .
President Donald Trump said he would provide details Thursday of what he and Elon Musk's Department of Government Efficiency (DOGE) claim are billions of dollars of wasteful and fraudulent ...
Flu activity remains "elevated" in the United States but is starting to show signs of abating, according to new federal data published Friday. The 2024-25 flu season was classified by the Centers ...
Copper(I) acetylide, copper carbide or cuprous acetylide, is a chemical compound with the formula Cu 2 C 2. It is a copper (I) salt of acetylene . It consists of Cu + cations and acetylide anions − C≡C − , with the triple bond between the two carbon atoms.
