2251. Potassium Citrate Tri(Hydrogen Peroxidate) [31226-90-1] C 6H 5K 3O 7.3H 2O 2

Anon., Jahresber., 1978, 75

Treatment of the citrate monohydrate with a 20% excess of 70% hydrogen peroxide gave a crystalline product which, after vacuum drying at 50 C corresponded approximately to the tri(hydrogen peroxidate). It decomposed violently when disturbed with a porcelain spatula.

  2. It is marginally detonable; requiring a 50 g tetryl booster.

The heat of decomposition of nitrobenzene was determined (360 490 C) as 1.76 kJ/g by DSC, and T ait24 was as 280 C by adiabatic Dewar tests, with an apparent energy of activation of 216 kJ/mol.
