  硝酸异丙酯
     Quantum chemical calculations at the HF/6-31G* and B3LYP/6-31G* levels have been carried out on five explosive sensitizers: ethyl nitrate (EN), n-propyl nitrate (NPN), isopropyl nitrate (IPN), 2-ethylhexyl nitrate (EHN), and tetraethylene glycol dinitrate (TEGDN). Theoretical studies have yielded a wealth of quantum chemical information on the molecular geometries, electronic structures, and energies of the title compounds.

     A static explosive experiment has been made on solidliquid double composite fuel-air explosive(FAE)(comprising Mg powder and isopropyl nitrate) after primary initiation. The running character of shock wave and the changing rule of overpressure space after FAE detonation have then been studied based on data analysis. Comparison on the explosion character of FAE with that of TNT,RDX,and desensitized RDX-Al enables the authors to obtain the relation between overpressure and specific impulse varying with distance.

Effect of paraffins C10-C13, C14-C17, C18-C23, tert-butyl hydroperoxide, cumyl hydroperoxide, and isopropyl nitrate as cetane number improvers for summer- and winter-grade diesel fuels, added in amount of 0.4-5 wt %, is studied.
      


Isopropyl nitrate is prepared by nitrating isopropanol with nitric acid at 100℃ in the presence of urea and ammonium nitrate. The yield of isopropyl nitrate can be obtained over 85% under the optimum reaction conditions. The purity of isopropyl nitrate can be over 98% based on the analysis of gas chromatography.

A static explosive experiment has been made on solidliquid double composite fuel-air explosive(FAE)(comprising Mg powder and isopropyl nitrate) after primary initiation.The running character of shock wave and the changing rule of overpressure space after FAE detonation have then been studied based on data analysis.Comparison on the explosion character of FAE with that of TNT,RDX,and desensitized RDX-Al enables the authors to obtain the relation between overpressure and specific impulse varying with distance.The authors have proved that the detonation reaction range FAE is greater than conventional explosives.In a certain distance from explosive center,the action time of FAE positive pressure is longer than conventional explosives and its specific impulse is greater than conventional explosives.
