Acetylene Acetylene (C2H2) is a colorless, highly flammable gas, with a characteristic ether and garlic-like smell. It is usually identified 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 feature causes the gas to have many unique features including a very high flame temperature when burned in an oxygen-rich atmosphere. Shifting 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. High Purity, Atomic Absorption Grade Acetylene is also a fuel gas for atomic absorption spectrophotometry analyzers. Acetylene is also extensively used in organic chemical and polymer synthesis. The classic acetylene synthesis involves adding water to calcium-carbide chips. This process will be common to anyone who has seen an antique miner’s helmet with flame illumination. While a large percentage of all commercial acetylene makes use of this method, a significant fraction of North American acetylene production relies on ethylene chemistry today.To purchase high quality PurityPlus Acetylene in the Richmond, Virginia area, you can contact us at (804) 644-4521 or through our online web form.
