The rate constants for the oxidative coupling of hydrophobic color-forming components with 4-amino-3-methyl-N-ethyl-N-(4-methylsulfonamidoethyl)aniline and concurrent deamination in 50percent aqueous dioxane were determined by spectrophotometric methods in relation to the pH of the medium.The capacity for coupling decreases in the following order: Derivatives of 1-hydroxy-2-naphthoic acid, 1-trichlorophenyl-3-benzoylaminopyrazolin-5-one, and pivaloylacetanilide.Deamination affords the strongest competition to coupling when pivaloylacetanilide is used.
