Potassium picrate (CAS NO.573-83-1) is used as chemical reagent, organic synthesis, pharmaceutical intermediate. Potassium picrate is used to determine the concentration of nonionic surfactants in water; materials detectable by this method are called potassium picrate active substances (PPAS).
As with other picrates, potassium picrate may be produced by the neutralization of picric acid with the corresponding carbonate. As picric acid is barely soluble in water the reaction must be done in an appropriate solvent like methanol. First dissolving the picric acid in methanol and then adding potassium carbonate will result in potassium picrate.Temperature control is important to prevent detonation or excessive methanol evaporation.
An explosive. Reaction with 2,2-dinitro-2-fluoroethoxycarbonyl chloride forms the explosive ester 2,2-dinitro-2-fluoroethyl-2,4,6-trinitrophenyl carbonate. When heated to decomposition it emits toxic fumes of K2O. See also PICRATES.
