Spectrophotometric Determination of the Ionization Constants of Aqueous Nitrophenols at Temperatures up to 225 °C

The UV-visible spectra of aqueous o-, m-, and p-nitrophenol were measured as a function of pH at temperatures from 50°C to 225°C at a pressure of 7 MPa. These were used to determine equilibrium constants for the acid ionization reac...
