Combustion of Acetylene
2C2H2 + 5O2 → 4CO2 + 2H2O
Ikhtisar
Acetylene burns in oxygen with an intensely hot flame reaching 3300 C, the hottest of any common fuel-oxygen combination. The oxy-acetylene flame is hot enough to cut and weld steel. Acetylene's triple bond stores significant energy that is released upon combustion.
