Procedure

0.0074 mol of KMnO4 is added in portions, with vigorous stirring, to a solution of 0.0037 mol of pentaerythrityl trinitrate (PETriN), 5.5 ml of benzene, 9 ml of water and 0.15 ml of Aliquat® 336. When the addition has ended, the temperature is kept at 15° C. for 2 hours. Aqueous hydrogensulfite solution is then added, the mixture is acidified with H2SO4 and the benzene layer is separated off. After removal of the solvent, 3-nitryloxy-2,2-bis(nitryloxymethyl)propionic acid (Tri-PA) is obtained as a solid residue, which is recrystallized several times from methylene chloride. Yield: 72%.
