1,5-二叠氮基-3-硝基氮杂戊烷合成反应动力学

摘要

1,5-Diazido-3-nitrazapentane was synthesized using diethylnitramine dinitrate and sodium azide as starting materials. The kinetic equation describing the synthesis reaction was established. The effect of temperature on the reaction rate was studied. The results indicate that the reaction is of the second order under the experimental conditions, rate constants of the reaction at the temperature of 90,93,95 and 98℃ are 2. 11×103,4. 72×103,6. 55×103, 1.20×102dm3 ? Mol-1 ? Min-1, respectively. The apparent activation energy E, and pre-exponential factor A of this reaction are 28. 87 Kj ? Mol-1 and 7. 67×1031 min-1, respectively.%以二乙醇-N-硝胺二硝酸酯和叠氮化钠为原料合成出1,5-二叠氮基-3-硝基氮杂戊烷,并建立了反应动力学方程,考察了温度对反应速率的影响.结果表明,在实验条件下1,5-二叠氮基-3-硝基氮杂戊烷合成反应为二级反应,在反应温度为90、93、95和98℃时,反应速率常数分别为2.11×103、4.72×103、6.55×103和1.20×102 dm3·mol-1·min-1；反应的表观活化能Ea为28.87 kJ/mol,指前因子A为7.67×1031 min-1.
