The kinetics of the reaction of 2,4,6‐triphenoxy‐1,3,5‐triazine with octylamine in N ‐methyl‐2‐pyrrolidone at temperatures between 10°C and 190°C was analyzed by HPLC. Data analysis with the help of a mathematical model showed first order kinetics in each reaction component for the three successive substitutions at the triazine ring. The calculated rate constants differ by orders of magnitude from each other, and their ratios show a pronounced temperature dependence due to the differing activation energies of 27,53 and 82 kJ · mol −1
