Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (7.9 in). Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm. Cut-off grinders are useless for these kinds of application. Robotic oxy-fuel cutters sometimes use a high-speed divergent nozzle.
An acetylene gas miner's lamp. A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C 2 H 2), which is created by the reaction of calcium carbide (CaC 2) with water (H 2 O). [1] Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable ...
Acetylene was also used from about 1898 for gas lighting on a smaller scale. [33] Illuminating gas was used for gas lighting, as it produces a much brighter light than natural gas or water gas. Illuminating gas was much less toxic than other forms of coal gas, but less could be produced from a given quantity of coal.
A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.
MAPP/oxygen was advantageously used in underwater cutting, which requires high gas pressures (under such pressures acetylene can decompose explosively, making it dangerous to use [5]). However, underwater oxy/fuel gas cutting of any kind has been largely replaced by exothermic cutting [6] because it cuts more quickly and safely.
A great example of uses for paper towels beyond cleaning messes is wrapping the disposable sheets around vegetables to keep them fresh and crisp in the refrigerator. Swathe greens, herbs, and ...
Calcium carbide is sometimes used as source of acetylene, which like ethylene gas, is a ripening agent. [19] However, this is illegal in some countries as, in the production of acetylene from calcium carbide, contamination often leads to trace production of phosphine and arsine .
