DISSOLVED ACETYLENE GAS

Pure acetylene is a unique gas with hazards that arise from its high energy bonds and flammability. These same properties give acetylene its value as a high temperature cutting and welding gas with a very wide range of applications. However, free acetylene can undergo explosive decomposition when compressed or overheated. Decomposition is a spontaneous reaction forming hydrogen and carbon (in the form of “lampblack” or “soot”). A considerable amount of heat and pressure is generated by this dissociation, which can produce high energy explosions.

Acetylene is normally dissolved in a solvent, typically acetone, at pressures…
