Acetylene

Acetylene is one of the important raw materials for organic synthesis. It is also a monomer for synthetic rubber, synthetic fibers and plastics, and is also used for oxyacetylene welding and cutting.

Pure acetylene is a flammable and toxic gas with a colorless, aromatic odor. The melting point (118.656kPa) is -80.8°C, the boiling point is -84°C, and the relative density is 0.6208 (-82/4°C). Acetylene is active and can undergo addition and polymerization reactions. It can burn at high temperature (3500 ° C) and strong light in oxygen.
