1 The kinetics of the hydrolysis of a dichlorotriazine reactive dye have been determined in aqueous buffer solutions at pH values between 8.50 and 13.47, at 24.0° and ionic strength I = 0.625. 2 The reaction order with respect to the concentration of the dye and the hydroxyl ions is a complex function of the reaction conditions. 3 Only in very dilute solutions the kinetics follow the mechanism postulated by Ackermann and Dussy [4]. 4 Several types of base catalysis can be detected, depending on conditions (pH, concentrations).
