脱氢松香酸甲酯氧化呋咱的合成与表征 |
| 4. | Its molecular structure is between tatb and btf . cl - 18 have amino and nitro groups like tatb , also have furoxans like btf
它的分子结构介于tatb和btf之间，有tatb分子中的硝基和氨基，也有btf分子中的氧化呋咱基团。 |
| 5. | In the recent years , the studies about benzofuroxans have already got import breakthrough . but we also know , benzofuroxan ( btf ) exists a problem of high sensitivity and using insecurely
但我们也知道，象btf这样的苯并三氧化呋咱又存在一个感度较高，使用不太安全的问题。 |
| 6. | This term has finished some work as follows : ( 1 ) we have synthesized aminonitrobenzodifuroxan which have not ever been seen in our country . and there are only one or two reports about it in america
本文主要做了以下工作： ( 1 )合成了氨基硝基苯并二氧化呋咱，这个化合物在国内尚未见报道，国外研究它的资料也很少。 |
| 7. | The development trend in explosives is towards high density , high energy and low sensitivity . the replacement of nitro groups by furoxan groups can result in increase of density , detonation velocity of explosives . so these superior performance of benzofuroxan system compounds have aroused much attention
含能材料的发展趋势是向着高密度、高能低感的方向发展。一个氧化呋咱基代替一个硝基，可以使含能材料密度提高，爆速增加，苯并氧化呋咱类化合物作为炸药所具有的这些优良特性引起了人们的高度兴趣。 |
| 8. | ( 6 ) 4 , 6 - diamino - 5 - nitrobenzofuroxan is designed to synthesis from trichlorobenzene through nitration aminatiom azidation and thermal decomposition . this compound is a new explosive . but we only got the intermediates of the first and second steps ( nitration , amination ) because the limit of time
( 6 )从均三氯苯出发，设计经硝化、氨化、叠氮化和脱氮四步合成4 ， 6 -二氨基- 5 -硝基苯并氧化呋咱，这是未见文献报道的新化合物，不过由于时间关系，我们只得到氨化这一步的中间产物即3 ， 5 -二氨基- 2 ， 4 -二硝基氯苯，这也是个未见文献报道的新化合物。 |
| 9. | We have more interest in benzofuroxans with amino and nitro substituents because the effect of pushing electron of amino group increases the bond energy of c - no2 , and there are strong intramolecular and intermolecular hydrogen bonds between amino and nitro group . these hydrogen contacts can make the molecular structure more stability . so aminonitrobenzodifuroxan may have good heat resistance and low impact sensitivity
所以我们对氨基硝基苯并氧化呋咱这类炸药更为关注，因为氨基的推电子效应使c - no _ 2键能增强，且氨基的氢原子与硝基的氧原子间形成强的分子内和分子间氢键，更增强了分子的稳定性，所以它们可能获得优良的热安定性和较低的感度。 |
