Tetraacetylethylenediamine TAED

Peracid Precursor Systems. Compounds that can form peracids by perhydrolysis are almost exclusively amide, imides, esters, or anhydrides (85). Two compounds were commercially used for laundry bleaching as of 1990. Tetraacetylethylenediamine (TAED) [10543-57-4] is utilized in over 50% of Western European detergents (5). The perhydrolysis reaction of this compound is shown in equation 19. TAED generates two moles of peracid and one mole of diacetylethylenediamine per mole of imide (93). [Pg.147]

Tetraacetylethylenediamine (TAED) and pentaacetylglucose (PAG) are employed as bleach pre-cursors of peracetic acid this allows the bleach to occur at a temperature lower than when hydrogen peroxide is used. Perhydro-lysis of the sulfonated aromatic ester, shown in Figure 2.38, gives superb bleach performance on textiles, probably due to the surface active properties of the compound. The acyl dialkyphosphates and the N-acylimidazoles are also effective peracetic acid precursors at low temperature. [Pg.62]
