1.取10g氧化钇加至500mL 50%乙酸溶液中,用蒸气浴加热。通常氧化钇可完全溶解,但有时也会有少许未反应氧化物残留在容器底部,则需过滤。滤液置于75℃水浴上加热以蒸去大部分溶剂。冷却,晶体析出。滤集晶体。将晶体移至玻璃皿中,置于装有粒状氢氧化钠及高氯酸镁的真空保干器中,抽真空进行干燥,得到水合醋酸钇。将水合醋酸钇放在真空干燥箱中于150℃干燥至恒重,得到醋酸钇。

2.取用上法制得的水合醋酸钇10g,放入500mL圆底烧瓶中,加入无水DMF 100mL,振摇,待醋酸盐溶解后,再加入无水苯150mL,蒸馏除去苯水共沸物,醋酸钇与DMF络合物(Y(CH3COO)3·DMF)析出。滤集结晶,用无水乙醚洗涤。将结晶放在装有无水氯化钙和五氧化二磷的干燥器中保存。最后将晶体放在真空干燥箱或阿布得哈顿干燥器中,在抽真空条件下于210℃加热除去DMF,制得醋酸钇。
