N,N,N′N′-tetraacetyletylenedyamine (TAED) as an activator for persodiums, in modern compositions of detergents and disinfectants

Abstract

The synthesis of N,N,N′,N′-tetraacetylethylenediamine (TAED) in two steps was approached, using as a basic raw material ethylenediamine, this one being acetylated in the first step with acetic acid to give N,N′-diacetylethylenediamine (DAED), DAED being acetylated afterward with acetic anhydride up to TAED; both steps of the process are accomplished in a xylene medium. The purification of the raw product is made from a mixture of acetic acid and ethanol, giving TAED with a purity that allows it to be used in detergent and disinfectant mixtures. The activation capacity of the peroxidic compounds was tested using sodium percabonate, as a single compound or in a mixture with TAED, on several bacterias.
