Acetylene (C2h2) Acetylene (C2H2) is a colorless, highly flammable gas, with a characteristic ether and garlic-like smell. It is commonly known 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 a number of unique features including a very high flame temperature when burned in an oxygen-rich atmosphere. Adjusting 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: PurityPlus Purified 2.6(for atomic absorption) 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 familiar to anyone who has seen an antique miner’s helmet with flame illumination. While a large percentage of all commercial acetylene utilizes this method, a significant fraction of North American acetylene production relies on ethylene chemistry today.To purchase high quality PurityPlus Acetylene in the Denver area, you can contact us at (303) 777-6671 or through our online web form.
