RI 6659 Flammability Characteristics Of Ethylene

The Bureau of Mines conducted ignition, flammability, and decomposition experiments on gas mixtures containing ethylene to determine its flammability characteristics at elevated pressures and ambient temperatures. Pure ethylene was found to propagate a decomposition reaction at 1,000 psig and ambient temperatures when ignited with 1 gram or more of guncotton in a 2-inch-id bomb. The decomposition products were primarily carbon, methane, and hydrogen.
