Pure acetylene gas has no smell, but because the calcium carbide raw materials used to produce acetylene contain a small amount of calcium sulfide and phosphide, solid industrial acetylene gas contains impurities such as phosphine and hydrogen sulfide and has an unpleasant garlic smell. Mainly used in metal welding and cutting, organic synthesis, atomic absorption spectroscopy, standard gas, calibration gas, synthetic rubber, and lighting.
Main uses: Acetylene can be used for lighting, welding and cutting metal (oxyacetylene flame). It is also the basic raw material for manufacturing acetic acid, synthetic rubber, synthetic fibers, etc.
Acetylene can produce high temperatures when burned, and the temperature of the oxyacetylene flame can reach about ℃, which is used for cutting and welding metals. Supplying an appropriate amount of air, it can be completely burned to emit bright white light. It can be used as a lighting source in places where electric lights are not popular or there is no electricity. Acetylene has active chemical properties and can undergo addition reactions with many reagents. Before the 1990s, acetylene was the most important raw material for organic synthesis, and it is still one of the important raw materials today.
