采用Y2 O3 为原料先制得无水YCl3 然后与异丙醇反应生成YCl3·3C3H7OH加合物 ,并采用自制异丙醇钠与之反应制备得到异丙醇钇 ,反应的最佳条件为 80℃回流 3～ 4小时 ,然后静置 12h以便NaCl的分离。在YCl3·6H2 O脱水制备YCl3 的过程中 ,采用醋酸酐脱水法 ,具有方法简单 ,污染小 ,且易于操作等特点 Y2 O3 was used as raw material to prepare anhydrous YCl3, then reacted with isopropanol to form YCl3 · 3C3H7OH adduct, and yttrium isopropoxide was prepared by the reaction of sodium isopropoxide with it. The optimum conditions of the reaction were 80 ℃ reflux 3 to 4 hours, then let stand 12h for the separation of NaCl. The dehydration of YCl3 · 6H2O during the preparation of YCl3, the use of acetic anhydride dehydration method, with a simple, less pollution, and easy to operate and so on
