Acetylene (C2h2)

Acetylene (C2H2) is a colorless, highly flammable gas, with a characteristic ether and garlic-like smell.  It is often used as a fuel gas for welding, cutting, and brazing. Acetylene has a distinct chemical property which is the triple-bond between its carbon atoms.  This triple-bond attribute leads to the gas having several unique features including a very high flame temperature when burned in an oxygen-rich atmosphere. Varying the feed ratio of oxygen and acetylene to an oxy-acetylene torch can produce a shielding atmosphere from oxidizing to carburizing, imparting different physical properties to working metal.

Acetylene grades we offer:

High Purity, Atomic Absorption Grade Acetylene is also a fuel gas for atomic absorption spectrophotometry analyzers. Acetylene is also widely used in organic chemical and polymer synthesis.

The classic acetylene synthesis involves adding water to calcium-carbide chips. This process will be recognized by anyone who has seen an antique miner’s helmet with flame illumination. While a large percentage of all commercial acetylene employs this method, a significant fraction of North American acetylene production relies on ethylene chemistry today.
