This compound looks like flat rectangular crystalline plates or sometimes in the form of prisms. The explosive properties of this compound were discovered by R. McGill at the NDRC Research Lab in Bruceton, Pennsylvania. It is somewhat powerful, having 126% the strength of TNT, and has a somewhat low sensitivity to impact.

Add 20 g of 2-nitro-2-(3',5'-dinitrophenyl)-propanediol-1,3 in several portions to 130 mL of fuming nitric acid in a small beaker, cooled to 5 °C with a salt-ice bath. After about 6 minutes all of the material should be dissolved and the temperature will have risen to 10 °C. Drown the mixture in 1.5 L of ice water and allow it to stand for 15 minutes. Decant off most of the ice water and collect the hardened, gummy material on a filter then wash it with water. Purify by dissolving in acetone and crystallize it by adding ethyl alcohol to the solution. The yield varies between 67% and 86%. You will need a graduated cylinder for measuring liquids, and a thermometer to monitor the temperature.
