Abstract English	Investigation of explosive decomposition of ethylene oxide (EO) at fixed initial experimental parameters (T = 100 C, P = 4 bar) in a 20-l sphere was conducted. Safety-related parameters, namely the maximum explosion pressure, the maximum rate of pressure rise, and the KG values, were experimentally determined for pure ethylene oxide and ethylene oxide diluted with nitrogen. Soot formation was experimentally observed.

Sicherheitstechnische Kenngrößen, nämlich der maximale Explosionsdruck, die maximale Druckanstiegsrate und die KG Werte wurden experimentell für reines Ethylenoxid und mit Stickstoff verdünntem Ethylenoxid bestimmt. Rußbildung wurde experimentell beobachtet.

Abstract English	Investigation of explosive decomposition of ethylene oxide (EO) at fixed initial experimental parameters (T = 100 C, P = 4 bar) in a 20-l sphere was conducted. Safety-related parameters, namely the maximum explosion pressure, the maximum rate of pressure rise, and the KG values, were experimentally determined for pure ethylene oxide and ethylene oxide diluted with nitrogen. Soot formation was experimentally observed.
Abstract German	Die explosive Zersetzung von Ethylenoxid (EO) wurde bei festen Versuchsparametern (T = 100 C, P = 4 bar) in einem 20-L-Kugelautoklav untersucht. Sicherheitstechnische Kenngrößen, nämlich der maximale Explosionsdruck, die maximale Druckanstiegsrate und die KG Werte wurden experimentell für reines Ethylenoxid und mit Stickstoff verdünntem Ethylenoxid bestimmt. Rußbildung wurde experimentell beobachtet.
