【摘要】 探讨了以乙二胺、乙酸、和乙酸酐作为原料,采用两步法在杂多酸(HSiW)催化剂作用下制备活性漂白剂四乙酰乙二胺(TAED)的合成工艺条件。得出两步法的最佳条件是:乙二胺:乙酸(物质的量)=1:2.5,反应温度约120℃,反应时间1.5h;乙二胺:乙酸酐(物质的量)=1:4,反应温度为140℃,反应时间4h。TAED的产率与杂多酸催化剂性能的好坏有较紧密的关系。更多还原

【Abstract】 This article which relates to processes for the production of activated bleacher TAED is prepared by the stock of ethylenediamin, aceticacid, anhydride, and the step of preparing TAED with HSiW as heteropolyacid catalyst react in two steps.The best reaction conditions of the experiment:the one temperature is 120℃ ,the other is 140℃;ethylenediamine and acetic acid in a mole ratio 1:2.5, reacting time 1.5 h and acetic anhydride in a mole ratio 1:4, reacting time 4h. The yield of the TAED closely relates to the property of the heteropolyacid catalyst.更多还原
