For oxyfuel cutting, heat treating and torch brazing applications

produced by the reaction of calcium carbide with water or as a by-product of ethylene production. Acetylene is dissolved in a solvent in a specially designed cylinder filled with a porous substance. Because the gas dissolves in matter, it is sometimes called "dissolved acetylene".

Acetylene's extremely high flame temperature (3100°C) makes it ideal for oxyacetylene cutting, heat treating and torch brazing. It is also used in organic synthesis in analytical laboratories and as a flame gas in analytical techniques such as atomic absorption (AA) spectroscopy. Sometimes it is used for chemically induced flower production.
