氢氧化铈(IV)是一种无机化合物,化学式为Ce(OH)4

制备

[编辑]

氢氧化铈(IV)可由碳酸铈(III)和醋酸反应后被过氧化氢氧化制备,其反应过程为[1]

Ce2(CO3)3 + 6 CH3COOH → 2 Ce(CH3COO)3 + 3 CO2↑ + 3 H2O
2 Ce(CH3COO)3 + 3 H2O2 + 4 H2O → 2 Ce(OH)3(OOH) + 6 CH3COOH
CH3COOH + NaOH → CH3COONa + H2O
2 Ce(OH)3(OOH) → 2 Ce(OH)4↓ + O2

其总反应为:

Ce2(CO3)3 + 6 CH3COOH + 3 H2O2 + 6 NaOH —343 K→ 2 Ce(OH)4 + 6 CH3COONa + O2↑ + 3 CO2↑ + 5 H2O

以硝酸铈(III)为原料,也有类似的反应:[2]

2 Ce(NO3)3 + 3 H2O2 + 6 NH3·H2O → 2 Ce(OH)3(OOH)↓ + 6 NH4NO3 + 2 H2O

反应产生红褐色的过氧化铈,煮沸后转化为氢氧化铈(IV):

Ce(OH)3(OOH) —Δ→ 2 Ce(OH)4↓ + O2
