摘要
对以工业铝为原料制备高纯异丙醇铝的不同纯化技术进行了研究，提出了成本低、能耗少、流程简单的纯化技术——萃取－络合法．研究表明，以某有机溶剂为萃取剂（用代号ＴＢ表示）、ＤＣＴＡ为络合剂可制得质量分数大于９９．９９９％的高纯异丙醇铝．
? Different purification techniques are studied for preparing high purity Al(OPr i ) 3 using industrial aluminium as raw materials. A novel and valuable purification technique-extraction complexation method is proposed. The results show that high purity Al(OPr i ) 3 ( w (Al(OPr i ) 3)>99.999%) can be obtained by this technique using a certain organic solvent (named TB) as extracting agent and DCTA as complex agent.
