An analytical study of the effect of pressure on the rate constant for the unimolecular decomposition of n-propyl nitrate is given. The Rice- Ramsperger-Kassel-Marcus theory is reviewed, and the present application is discussed in detail. Limitations on application of this model are also discussed. It is concluded that the initial decomposition reaction of nitrate esters cannot be the rate determining step for the observed variation of burning rate with pressure.

The idea of this book is to present the up-to-date research results on Nitrate Esters as explosive materials. It covers many aspects including the material structures, nitrating agent, chemical synthesis devices, preparation technology, and applications etc. In particular, this work sheds light on the comprehensive utilization and thorough destruction of the used Nitrate Easters which is crucial for preventing repeated pollution. This is a highly informative and instructive book providing insight for the researchers working on nitrating theory, energetic materials and chemical equipments.

The thermal decomposition of gaseous Et nitrate (I) was studied at 161 deg, 181 deg, and 201 deg C. The data (pressure of the particular component/initial pressure of I) were plotted according to a first-order reaction. The results at 161 deg and 181 deg C were divisible into 2 parts, an initial linear portion and a second linear portion of higher slope; the change in slope occurred at about 50 and 201 deg C did not permit division. The effects of NO sub-2, Et nitrite (II), and Hg on the decomposition rate are discussed. The NO sub-2 content usually did not exceed 10% of the initial amount of I; the NO sub- 2 pressure variation was attributed to NO sub-2 formation from the decomposition of I and NO sub-2 consumption by EtOH, a dissociation product of II. No formed directly from the decomposition of II. The presence of Me nitrite and MeNO sub-2 was established at the end of the reaction. Peak pressures of II occurred at 70 and 62% of the initial concentration of I at 161 deg and 181 deg C, respectively; more II was formed than could be accounted for by the NO sub-2-EtOH reaction. The decompostion mechanism of I cannot be completely explained by attributing the point of molecule fracture of the O-N bond.
