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.
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 the 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.

Yes. Acetylene is a colorless, extremely flammable gas at normal temperature.
Acetylene can be used for lighting, welding and cutting metals (oxyacetylene flame), and it is also the basic raw material for the manufacture of acetaldehyde, acetic acid, benzene, synthetic rubber, and synthetic fibers.
