In this study, the coupling kinetics of sulfanilamid diazonium salt with 1‐naphthylamine has been studied by spectrophotometric method. In the experiments conducted at constant temperature, 25°C, pH has been varied between 2.2−3.4, reactant concentration between 1.25 × 10 −5 − 5 × 10 −5 M, and ionic strength between 0.1−1 M. The reaction has been confirmed to be of second‐order and rate constants and the dissociation constant of 1‐naphthylamine have been calculated. © 1993 John Wiley & Sons, Inc.
