Preparation

The compound was first synthesized in 1924 by Oldřich Turek. [3] It can be prepared by the reaction of 1,3,5-trichloro-2,4,6-trinitrobenzene with sodium azide. 1,3,5-trichloro-2,4,6-trinitrobenzene is obtained from the nitration of 1,3,5-trichlorobenzene with nitric acid and sulfuric acid. [3]

Another route uses the nitration of 1,3,5-triazido-2,4-dinitrobenzene. [1]

Properties

Chemical Properties

Even at low temperatures, the compound slowly decomposes by giving off nitrogen gas, converting into benzotrifuroxan. This reaction proceeds quantitatively within 14 hours at 100 °C. [3] As a solution in m-xylene, first order kinetics were observed for the decomposition, with a half-life of 340 minutes at 70 °C, 89 minutes at 80 °C, and 900 seconds at 100 °C. [4]

<span class="mw-page-title-main">Nitrogen</span> Chemical element, symbol N and atomic number 7

Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth.

<span class="mw-page-title-main">Nitric acid</span> Highly corrosive mineral acid

Nitric acid is the inorganic compound with the formula HNO3. It is a highly corrosive mineral acid. The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%.

In organic chemistry, nitration is a general class of chemical processes for the introduction of a nitro group into an organic compound. The term also is applied incorrectly to the different process of forming nitrate esters between alcohols and nitric acid. The difference between the resulting molecular structures of nitro compounds and nitrates is that the nitrogen atom in nitro compounds is directly bonded to a non-oxygen atom, whereas in nitrate esters, the nitrogen is bonded to an oxygen atom that in turn usually is bonded to a carbon atom.
