Study on synthesis of TAED;

The research results show that these organic acetyl agents initiatively , for example: TAED, TAGU,ισο-NOBS,PAG, can obviously activate hydrogen peroxide; thus, the efficiency of hydrogen peroxide bleaching can be advanced greatly.

The effects of bleaching variables such as chemical dosage,bleaching time ,temperature,pH value and the synergy of the activate agent TAED and acetic anhydride on the brightness of the bleached pulp were studied.

Research activation effect of tetraacetylethylenediamine on sodium perborate;

Synthesis of tetraacetylethylenediamine by coupling technique of reaction and rectification process;

Tetraacetylethylenediamine (TAED) is known as an additive for washing compositions containing an oxygen yielding bleaching agent.

The bleaching activator tetraacetyl ethylenediamine(TAED) was prepared by a two-step method, That is, The reaction of ethylene diamine with acetic acid formed diacetyl ethylenediamine which reacted further with acetic anhydride, thus forming TAED.

Study on synthesis of tetraacetylenediamine under microwave irradiation;

The tetraacetylenediamine (TAED) is one of the activators at lower temperature, which could be syn-thesized under reasonable technical conditions with two-step meathod.
