瑞典科学家发现可制成更好火箭燃料的新分子

[据澳大利亚space-travel网站2010年12月22日报道] 瑞典科学家称发现了一种可以制造新火箭燃料的分子，其效率比现有燃料提高20%-30%。
瑞典研究理事会22日发布的报告表示：瑞典皇家理工学院的研究者们发现了由氮氧基组成的这种新的分子，将其命名为trinitramid。
研究者表示，燃料效率提高可转化为火箭更大的运载量。瑞典皇家理工学院的物理化学教授陶瑞•布林克（Tore Brinck）说“据粗略估算，火箭燃料的效率每增加10%，火箭的载重量就能成倍增加。”“此外，分子中只有氮和氧，这种火箭燃料不污染环境。”
“这种燃料比目前的固体火箭燃料好得多，使用固体火箭燃料，每次发射航天飞机任务都要释放550吨的浓盐酸。”“而新分子的独特之处在于它只含有氮和氧。此前我们只知道有8种这类混合物，而且大部分是在18世纪发现的。”
科学家们正在设法在试验管中制造出足够的混合物，以便检测和分析。布林克说，“尚需观察这种分子在固体状态下的稳定性。” （中国航天工程咨询中心 许红英 侯丹）

Discovery of New Molecule Could Lead to More Efficient Rocket Fuel
ScienceDaily (Dec. 22, 2010) — Trinitramid is the name of the new molecule that may be a component in future rocket fuel. This fuel could be 20 to 30 percent more efficient in comparison with the best rocket fuels available today, according to researchers. The discovery was made at the Royal Institute of Technology (KTH) in Sweden.
"A rule of thumb is that for every ten-percent increase in efficiency for rocket fuel, the payload of the rocket can double. What's more, the molecule consists only of nitrogen and oxygen, which would make the rocket fuel environmentally friendly. This is more than can be said of today's solid rocket fuels, which entail the emission of the equivalent of 550 tons of concentrated hydrochloric acid for each launch of the space shuttle," says Tore Brinck, professor of physical chemistry at KTH.
Working with a research team at KTH, he discovered a new molecule in the nitrogen oxide group, which is not something that happens every day. It was while the scientists were studying the breakdown of another compound, using quantum chemistry computations, that they understood that the new molecule could be stable.
"As mentioned, what is specific to this molecule is that it contains only nitrogen and oxygen. Only eight such compounds were previously known, and most of them were discovered back in the 18th century. This is also clearly the largest of the nitrogen oxides. Its molecular formula is N(NO2)3, and the molecule is similar to a propeller in shape," says Tore Brinck.
The research team, consisting of Martin Rahm and Sergey Dvinshikh as well as Professor Istvan Furó , besides Tore Brinck, has now shown how the molecule can be produced and analyzed. The scientists have also managed to produce enough of the compound in a test tube for it to be detectable.
"It remains to be seen how stable the molecule is in a solid form," says Tore Brinck.
It was during work to find an alternative to today's solid rocket fuel that the researchers found the new molecule. The findings are now being published in the journal Angewandte Chemie International Edition.

1个N原子周围三个3个NO2，不知道稳定不
六氧化四氮？
记者跑科普线的就专业点。别看到什么就大忽悠。还什么分子只有氮氧的就没污染，高中生都不信。 要说高能分子那是多了去了，高级点的都靠变形的价健来储能。但不是越高就越好，起码要稳定燃烧吧。
目前最先进固体燃料的不是公认的HTPB和NEPE吗？
使用固体火箭燃料，每次发射航天飞机任务都要释放550吨的浓盐酸
氮氧化合物用下来，多半是顺便产生点儿硝酸。

高浓度有危害，不过吹散之后相当于闪电固氮的作用，宏观上讲对植物生长有好处，
