Potentiometric pH measurements in aqueous solutions of carboxylic acids were carried out at temperatures from 323 K to 673 K and pressures from 23 MPa to 32 MPa by a flow-through electrochemical cell. New data of the molal ionization constants for the acids was determined. Effect of temperature and pressure on the ionization constants is discussed.
