Acetylene (C2H2) is a colorless, flameless gas with an odor like garlic. It can decompose spontaneously if the pressure exceeds 15PSIG. Acetylene produces one of the hottest gas flames known, having a temperature of 4,000 degrees Fahrenheit when burned with air and approximately 6000 Fahrenheit when burned with oxygen.

Unlike other gases offered, acetylene is not an element. It is a simple compound made up of approximately 92.3% carbon and 7.7 percent hydrogen. It is highly soluble in certain liquids, and this principle is utilized in dissolving acetylene in cylinders containing porous filler and filled with acetone.

Acetylene Applications

The major uses of acetylene, C2H2, are as a combustible gas in welding, heating and cutting applications and as building blocks for hydrocarbon products in the chemical industry.
