摘要
具有高张力和笼状结构的四环庚烷(QC)是很具潜力的自燃类碳氢燃料。研究了无溶剂条件下公斤级QC的合成工艺。测试了QC/白色发烟硝酸(WFNA)和QC/N2O4的自燃性能。结果表明,反应16 h和分离提纯后,QC产品的纯度和收率能分别达到99.5%和96.2%,单批产量为2 kg,QC/WFNA和QC/N2O4的点火延迟时间分别为98 ms和29 ms。固体纳米颗粒的添加能促进自燃性能,纳米硼、碳、铝可缩短点火延迟时间,添加质量分数为0.25%的纳米硼/碳/铝后点火延迟时间分别为68/73/75 ms(发烟硝酸)和18/27/33 ms(N2O4),证明QC可作自燃类高能液体推进剂使用。
Quadricyclane( QC) possessing high strain and caged structure is a very promoting spontaneous ignition type hydrocarbon fuel.The synthesis process of QC in kilogram scale was studied under the condition of no solvent. The spontaneous ignition performance of QC /white fuming nitric acid( WFNA) and QC / N2O4 was measured. After 16 h-reaction and further purification,the purity and yield of QC product can reach 99. 5% and 96. 2%,respectively. The batch production is 2 kg. The ignition delay time of QC / WFNA and QC / N2O4 are 98ms and 29 ms,respectively. The addition of boron,carbon and aluminum nanoparticles can improve the spontaneous ignition performance.The boron,carbon and aluminum nanoparticles can shorten the ignition delay time. After adding the 0. 25% mass fraction of boron / alumium / carbon nanoparticles,the ignition delay time is 68 /73 /75 ms( WFNA) and 18 /27 /33 ms( N2O4),respectively,proving that QC can be used as a kind of high-energy liquid propellant.
