Dipicryl sulfone is a moderately sensitive high explosive used in primers, detonators, shells, torpedoes, and bombs. The proper scientific name is 1,1'-sulfonylbis[2,4,6-trinitro-benzene, other names include 2,2',4,4',6,6'-hexanitrodiphenyl sulfone; bis(2,4,6-trinitrophenyl) sulfone; picryl sulfone; and HNDPhSo. It is rather stable to heating which makes it a good candidate for a verity of applications, but its industrial method of preparation is rather lengthy making it commercially undesirable. It was used primarily by the Germans starting around the time of WWI. It is not reactive with metals and forms no salts. This explosive lies in the middle in terms of sensitivity between the usual primary explosives and secondary explosives. It is also quite stable to electric shock and static.

Into a 400-mL beaker combine 34 g of dipicryl sulfide and 11 g of chromium trioxide in 149 g of 95% nitric acid. Heat the solution to 70 C while stirring and continue heating and stirring for 2 hours. Add 15 mL of water to the suspension and allow it to cool to 40 C. While still hot filter to collect the product, wash thoroughly with hot water to remove all traces of acid, and allow to dry. Yield of dipicryl sulfone is nearly 100%.
