Bleaching Activators as Acylating Agents kinetics of the acetylation of piperidine by some bleaching activators

Abstract

Abstract The bleaching activators 1,5‐diacetyl 2,4‐dioxo‐hexahydro‐1,3,5‐triazine (DADHT), tetraacetyl ethylenediamine (TAED), tetraacetyl glycolurile (TAGU), N,N′‐diacetyl N,N′‐dimethyl urea (DDU) and pentaacetyl glucose (PAG) are efficient acetylating agents which convert primary and secondary amines into their N‐acetyl derivatives. The rates of the reactions of the bleaching activators mentioned with piperidine were determined in the temperature range 20 to 90°C using dioxane as the solvent. The kinetic constants can be regarded as rough measures of the activity of the bleaching activators.
