THE EFFECT OF SOLVENT AND TEMPERATURE ON PROTONATION CONSTANTS OF DL-PHENYLALANINE IN DIFFERENT AQUEOUS SOLUTIONS OF METHANOL AT DIFFERENT TEMPERATURES

This research work has two sections. In first section, the equilibrium constant for protonation processes of DL-phenylalanine (K1, and K2) were determined in binary mixed solvents of water–methanol, containing 0, 10, 20, 30, 40, 50, 60, 70, and 80 % (v/v) methanol, at T = 298.15 K and constant ioni...
