Study of purification of Al(OPr i) 3 by extraction complexation method |

Abstract: | ? 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. |
