Discovery of new molecule can lead to more efficient rocket fuel
 
Trinitramid – that's the name of the new molecule that may be a component in future rocket fuel. This fuel could be 20-30 percent more efficient in comparison with the best rocket fuels we have today. 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.

Неужели тринитрамид термодинамически устойчив? Уже динитрамид аммония разлагается на обычном свету.
Хим.формула этого вещества получается N(NO2)3, итого 4 атома азота и 6 кислорода, притом, три связи азот-азот, как в гидразине или динитрамиде аммония. Подозреваю, что он устойчив только при отрицательных температурах.

Researchers at the Royal Institute of Technology (KTH) discovered the new molecule in the nitrogen oxide group and dubbed it trinitramid, a release from the Swedish Research Council reported Wednesday.

More efficient fuels translate into bigger rocket payloads, the researchers said.

"A rule of thumb is that for every 10 percent increase in efficiency for rocket fuel, the payload of the rocket can double," Tore Brinck, professor of physical chemistry at KTH, said. "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."

"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," he said.

The scientists have managed to produce enough of the compound in a test tube for it to be detectable and subject to analysis.

"It remains to be seen how stable the molecule is in a solid form," Brinck said.
