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.

Process

Acetylene is manufactured commercially by reaction between calcium carbide and water, and as a by product of ethylene production.

Applications

Scientific Research

Acetylene is used with high purity synthetic air or nitrous oxide as a fuel for the flame in atomic absorption flame spectroscopy. This is used in water, soil, food and biological research laboratories where sensitivity and accuracy of results are important.

Industrial

Acetylene is most commonly used in combination with oxygen for cutting or welding materials such as mild steel, where the standard industrial grade is sufficient. Acetylene with low phosphine levels is required for lead brazing or welding.

Plants

Acetylene is used in the cultivation of plant; it improves the forming of new flowers.

Energy

Acetylene is used as a component in calibration gases for the gas, oil as well as chemical industry.
