Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". [12][13] It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K 2 C 2), which reacted ...
History of manufactured fuel gases. The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century. These "synthetic fuel gases " (also known as "manufactured fuel ...
Acetylide. 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. The term is also used, more loosely, for any compound obtained in the same way from an acetylene derivative RC≡CH, where R is some organic side chain.
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 alternate name "silver carbide" is rarely used ...
Oxy-acetylene Welding (OAW) station. Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, biodiesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and ...

Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform -like pleasant mild smell [3] and sweet taste. [9]
Polyacetylene (IUPAC name: polyethyne) usually refers to an organic polymer with the repeating unit [C2H2]n. The name refers to its conceptual construction from polymerization of acetylene to give a chain with repeating olefin groups. This compound is conceptually important, as the discovery of polyacetylene and its high conductivity upon ...
