Acetylene


Acetylene


Acetylene is the chemical compound with the formula C2H2. Acetylene is a colorless, combustible gas with a distinctive odor, similar to garlic. Acetylene gas is created by the chemical reaction between calcium carbide and water. This reaction produces a considerable amount of heat, which must be removed to prevent the acetylene gas from exploding. Acetylene is a highly flammable gas.

Acetylene gas is filled into specially designed cylinders that are constructed of a solid core. This core is constructed with an absorbent, porous material, and a small amount of acetone. The acetylene gas is discharged into the cylinders where it is dissolved in liquid acetone. Once dissolved, it loses its explosive capability, making it safe to transport. When the cylinder valve is opened, the pressure drop causes some of the acetylene to vaporize into gas again and flow through the connecting hose to the welding or cutting torch. The cylinders must be stored vertically to ensure the dilution of the acetone.
