Abstract
In this paper explosion limits and induction periods for the explosion of ethyl azide in the presence of diethyl ether are reported and compared with data for pure ethyl azide. From the explosion limits certain deductions are made regarding the rate of loss of heat from the reaction flask. From the induction periods calculations of the heat of reaction are made. These give fairly consistent results over the range of temperatures, pressures, and compositions used, and are believed to offer further support to the contention that the explosion of ethyl azide is a thermal explosion. The heat of reaction found seems to be consistent with thermochemical data on related compounds. The method of calculation of the heat of reaction is applied to data of Appin, Chariton, and Todes on methyl nitrate. In this case the heat of reaction found from the explosion is inconsistent with thermochemical data, and it is concluded that the explosion of methyl nitrate cannot be a thermal explosion.
