Aug 12, 2021· Acetylene is a gas composed of 92.2% (by weight) carbon (C2) and 7.8% hydrogen (H2). The reason that the gas burns so hot is because of the mix of carbon and hydrogen. Acetylene is distributed in cylinders or tanks in a dissolved (in acetone), liquid state. Acetylene tanks can not (by law and common sense) be filled with any other type of gas.

Acetylene - Wikipedia

Discovery. Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K 2 C 2), which reacted with water to release the new gas.
