製備
- 6CH3COOH + Nd2O3 → 2Nd(CH3COO)3 + 3H2O
- 3CH3COOH + Nd(OH)3 → Nd(CH3COO)3 + 3H2O
- 6CH3COOH + Nd2(CO3)3 → 2Nd(CH3COO)3 + 3H2O + 3CO2↑
乙酸和釹鐵硼的反應也可以得到乙酸釹:
- 20CH3COOH + Nd2Fe14B → 2Nd(CH3COO)3 + 7Fe(CH3COO)2 + 10H2 + B
- NdCl3 + 3Na(CH3COO) → Nd(CH3COO)3 + 3NaCl
金屬釹和丙二酸在180°C反應,伴隨着脫羧反應,可以得到無水乙酸釹。[1]
