ACETYLENE (C2 H2)

Acetylene

  General

Acetylene is a highly flammable & colourless gas. It poses fire and explosion hazards at very low concentrations. Acetylene is an unstable gas and is filled in cylinders packed with a porous mass. Generically it is sold as dissolved Acetylene. Special care is required during examination & filling the cylinder. Commercial production of Acetylene is done using Calcium Carbide.

Applications

Acetylene when mixed with Oxygen burns violently & produces an extremely hot flame. It is used very commonly for metal cutting in the steel industry. Acetylene produces a highly luminous flame.ln line with these characteristics, following are the most common applications:

  • Metal Fabrication
  • Marine Lighting
  • Atomic Absorption
