Hexanitro hexaazaisoUlu titanium (British :Hexanitrohexaazaisowurtzitane abbreviated designation: HNIW, CL-20) is a thing having the biggest power in practical use, a mass-produced explosive as of 2006.
It was a calculation of the structure of the compound as the ideal explosive by the intramolecular orbit calculation with the super computer that was performed in the beginning when this material was known to have special blood relationship for a compound. In that way synthetic law is studied after having decided molecular structure earlier and is a thing put to practical use. I do not exist naturally.
Ulu titanium (with wurtzitane, ウルツィタン) which there is in the name is the name of the material becoming the nucleus and is associated with structure resembling crystal structure of the mineral one of the blende wurtzite (wurtzite) (thus, "titanium" of the end of a word is not a thing pointing at metal titanium (British :Titanium)). In addition, Ulu titanium is called Aisan (iceane), but this depends on structure being similar to snow crystal structure.
Because molecular structure in itself has a distortion in addition to having six nitro groups, I contain extremely high energy, and destructive power as the gunpowder is big. In addition, oxygen has good 12 and oxygen balance, and free carbon and carbon monoxide are hard to occur at the time of combustion for six carbon. Therefore free carbon burns with atmospheric oxygen even if I do not add an antiphlogistic when I use it as a propellent of the bullets, and, in addition to the harmlessness of combustion gases, the second flame to occur becomes small and shows that even an aspect except simple gunpowder is superior gunpowder.
Four kinds of an alpha type, a beta type, a gamma type, the epsilon type are to the crystal, but only a stable ε type crystal is used as an explosive without the former three persons being too sensitive, and enduring practical use. The use is wide and is used in bullets as raw materials of the multi-base gunpowder from the bursting charges such as cannonballs.
It is 2.04, and the RE coefficient that exchanging destructive power to the trinitrotoluene (TNT) ratio is notified about to do it with 190% of TNT conversion by the advice about the hazardous materials transportation of the United Nations.
History
- I was composed in 1987 by Arnold Neilson doctor (Arnold Nielson) of Thiokol company (Thiokol). An expensive palladium catalyst was necessary for composition at the initial stage, and cost became than 1 pound 3,000 dollars very highly.
- 48 members of the study team including the Arnold Neilson doctor win a team prize by invention of HNIW on December 16, 1993.
- The number called CL-20 where Thiokol company made a contract of the joint development plan with NAWCWD(Naval Air Warfare Center Weapons Division) on June 19, 1996 succeeded in reduction in cost to 1 pound 100 dollars by collaborative investigation given from NAWCWD at this time.
- I dissolve hexanitro hexaazaisoUlu titanium of an alpha type, a beta type, the gamma type with a methanol solvent in Asahi Chemical Industry in 1999, and the fourth ε type crystal is discovered by letting you vaporize a solvent and precipitate a crystal.
Manufacturing method
Like the following expressions, I make Ulu titanium structure from glyoxal and benzylamine and acetylate it after having removed benzylic and I put nitration last and produce it.
