Thermal stability and deflagration of ethylene oxide

Some initiating causes of ethylene oxide decomposition are examined. Experimental data are presented for thermal decomposition limits, autoignition temperature and minimum ignition energy. It is shown that flame propagation through liquid filled lines may occur via decomposition of a vapor pocket. Insulation fires are discussed in terms of a series of exothermic reactions initiated by low tempertaure formation of polyethylene glycols. Some case histories are reviewed.
