Acetylene
From Encyclopædia
{uh-set'uh-leen} Because of its triple bond, acetylene easily undergoes addition reactions. Vinyl
chloride is manufactured from acetylene by the addition of hydrogen
chloride. Similar additions with
acetic acid, and with hydrogen cyanide, yield vinyl
acetate and
acrylonitrile. Both compounds are important in the production of artificial fibers and
plastics. Acetylene gas is used in
metal cutting and welding because of its high combustive temperature.
