Article abstract of DOI:10.1002/kin.550251102

In this study, the coupling kinetics of sulfanilamide 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 constants of 1-naphthylamine have been calculated.
