Why is Octanitrocubane such a high energy molecule?

Why is Octanitrocubane such a high energy molecule?

Octanitrocubane is thought to have 20–25% greater performance than HMX (octogen). This increase in power is due to its highly expansive breakdown into CO2 and N2, as well as to the presence of strained chemical bonds in the molecule which have stored potential energy.

What explosive has the highest detonation velocity?

EPX-1 has the highest detonation velocity of all the studied plastic explosives. The calculated detonation pressure and heat of detonation of EPX-1 are in the same level of Semtex 10 and higher than the rest of the studied plastic explosives.

Is Dynamite a high or low explosive?

Dynamite – a high explosive used for blasting, consisting essentially of a mixture of, but not limited to, nitroglycerin, nitrocellulose, ammonium nitrate, sodium nitrate, and carbonaceous materials.

Is dynamite or TNT stronger?

You may see some explosives labeled “TNT” that look like dynamite. TNT stands for trinitrotoluene, which is also an explosive but quite different from dynamite. Dynamite is actually much more powerful than TNT.

What is cubane used for?

It is the simplest hydrocarbon with octahedral symmetry. Having high potential energy but kinetic stability makes cubane and its derivative compounds useful for controlled energy storage. For example, octanitrocubane and heptanitrocubane have been studied as high-performance explosives.

Why is Semtex called Semtex?

Semtex was invented in the late 1950s by Stanislav Brebera and Radim Fukátko, chemists at VCHZ Synthesia, Czechoslovakia (now Czech Republic). The explosive is named after Semtín, a suburb of Pardubice where the mixture was first manufactured starting in 1964.

What are two chemicals that explode when mixed?

When you mix the two together you get sodium acetate and water. You also get carbon dioxide, which is a gas. The bag puffs up because carbon dioxide is a gas and takes up a lot of space. Eventually the bag isn’t big enough to hold all that carbon dioxide gas so it explodes!

What are 2 types of high explosives?

High explosives will be referred to Type E explosives, and there will be three sub-types in this group:

  • 1 – blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
  • 2 – perforating explosives (intended for use in the oil and gas well industry);

What is the most explosive thing in the world?

Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.

What makes a cubane explosive an octanitrocubane?

A cubane with a nitro group on each carbon is called octanitrocubane. Several factors are important in making a good explosive. The decomposition must be energetic. In cubane derivitives, the strain energy ensures a very energetic decomposition. The number of molecules that result should be large.

What is the detonation velocity of octanitrocubane?

In addition, octanitrocubane produces no water vapor making it less visible, and both the chemical itself and its decomposition products ( nitrogen and carbon dioxide) are considered to be non-toxic. Octanitrocubane has a detonation velocity of 10,100 m/s, making it the fastest known explosive.

Is it possible to make octanitrocubane in the laboratory?

Small amounts have been synthesized in the laboratory, but not enough for performance testing as an explosive.

What is the molecular formula for octanitrocubane?

Infobox references. Octanitrocubane (molecular formula: C 8(NO 2) 8) is a high explosive that, like TNT, is shock-insensitive (not readily detonated by shock).
