NONA is an acronym for nonanitroterphenyl. The more scientific names of 2,2',2",4,4',4",6,6',6"-nonanitroterphenyl and 1,1':3',1''-terphenyl, 2,2',2'',4,4',4'',6,6',6''-nonanitro- have also been used. This substance has the appearance of light yellow crystals. Although its stability to shock and friction is not very high, it has good thermal stability and low volatility. This substance has found a use as a booster explosive in space applications. This information was classified, but now it is free.

Prepare a glassware setup for addition and refluxing with a round bottomed 500-mL Florence flask. Dissolve 30 g of thoroughly dried picryl chloride in 50 mL of anhydrous nitrobenzene in the flask. Gently heat the solution to reflux. Prepare a mixture of 5.6 g of 1,3-dichloro-2,4,6-trinitrobenzene and 13 g of electrolytic copper dust. This mixture will need to be constantly stirred to keep the copper in solution homogenous, add it from the addition funnel over a 15 minute period. Continue refluxing for an additional 10 minutes, then filter the solution while it is still hot. Wash the inorganic residue on the filter with several small portions of hot nitrobenzene. The filtrate and washings should then be concentrated on an oil bath under reduced pressure to a thick syrup. Add 350 mL of toluene and reflux the mixture for 15 minutes. Filter the hot liquid, the dark brown residue, about 8 g, should be suspended in 350 mL of toluene, and the mixture refluxed again for 15 minutes, and filtered while hot. The residue on the filter should be a brown powdery solid weighing about 5.5 g after drying in air. The combined filtrates and washings are filtered through a 3 inch pad of silicic acid on a 90-mm sintered glass funnel, and the absorbent pad is washed with toluene until a bright yellow band has moved near the bottom of the filter. The filtrate is evaporated to dryness, the residue is added to 300 mL of toluene and refluxed for 15 minutes and filtered. The product recovered on the funnel should be a tan crystalline material. This material is purified in two portions by chromatography on silicic acid-infusorial earth, yielding about 2.0 g of a light yellow crystalline solid that if there is any decency in the world will be NONA. You will need a graduated cylinder for measuring liquids, and a magnetic stirrer for mixing.
