Acetylene

Acetylene is used as a raw material for the production of electronically conducting plastics, such as polyacetylene.

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.

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.

Acetylene is used in organic synthesis (laboratory work) as well as in chemical synthesis.

Acetylene is used as carbon source in the production of molecular manufacturing like fullerenes; well known examples are bucky balls or carbon nanotubes.

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

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

Acetylene is still used in some lighthouses as light fuel source.

Acetylene is one of the components in lung testing gases.
