制备

乙酸钕可由乙酸氧化钕碳酸钕氢氧化钕反应得到:[4]

6CH3COOH + Nd2O3 → 2Nd(CH3COO)3 + 3H2O
3CH3COOH + Nd(OH)3 → Nd(CH3COO)3 + 3H2O
6CH3COOH + Nd2(CO3)3 → 2Nd(CH3COO)3 + 3H2O + 3CO2

乙酸和钕铁硼的反应也可以得到乙酸钕:

20CH3COOH + Nd2Fe14B → 2Nd(CH3COO)3 + 7Fe(CH3COO)2 + 10H2 + B

氯化钕乙酸钠在水溶液中反应,也能生成乙酸钕:[5]

NdCl3 + 3Na(CH3COO) → Nd(CH3COO)3 + 3NaCl

金属钕和丙二酸在180°C反应,伴随着脱羧反应,可以得到无水乙酸钕。[1]
