Acetylen (chemical formula C₂H₂) is a synthesis gas.
This hydrocarbon is either produced from the reaction between calcium carbide and water, either of chemical origin.
Colorless, it is odorless if pure but otherwise has a strong garlic odor (due to the phosphine in calcium carbide).
Acetylene is an unstable gas, highly combustible and needs to be stabilized.
Here are some of its applications, by activity:
Mechanical and metal fabrication
Combined with pure Oxygen, its flame temperature can reach more than 3000°C (or 5400°F).
It can thus be used to weld various metals (steel, stainless steel, etc.), to heat, form or treat them.
Acetylene is also used to cut steel.
Acetylene ALPHAGAZ 1 (99.6% pure) is used in Atomic Absorption Spectrometry (AAS).
Another of its applications is chemical synthesis.
Glass and metals
The acetylenic flame is used to lubricate production moulds (glass, aluminium, etc...).
