摘要：四乙酰乙二胺(TAED)由于其較好的漂白活化作用而應用日益廣泛。本文對目前漂白活化劑TAED的合成方法的研究進行評述，綜述了以乙二胺、乙酸、乙酸酐為原料，采用質子酸、有機堿為催化劑，或以微波誘導為手段制備TAED的研究進展。實驗中分別對一系列質子酸和有機堿進行了催化效果比較，初步探討了質子酸和有機堿可能的催化機理，為進一步開發適用于工業化合成TAED的催化劑提供了具有一定參考價值的基礎數據。

Abstract：Tetraacetylethylenediamine (TAED) as a good bleach activator is used widely more and more. In this paper the synthetic method about TAED is reviewed. It is introduced that with acetic acid, acetic anhydride as raw materials TAED is prepared and proton acids and organic bases is used as catalysts. The catalytic activities of a series of organic bases and proton acids is determined and compared, and their catalytic mechanism is discussed. The results can be used for the further development and industrialized production of TAED.
