1 The kinetics of the hydrolysis of three monochlorotriazine reactive dyes have been determined in alkaline buffer solutions at 60°, 80° and 98° (ionic strength I = 0.0625). 2 The kinetic results as well as diffusion measurements in aqueous solution indicated that these dyes form aggregates at dye concentrations at 6 · 10 −4 , but practically not at 6·10 −6 moles/l. 3 The reaction order with respect to hydroxyl ions has been determined. The influence of general base concentration was negligible.
