乙酸锌,二水制备

1.醋酸、氧化锌与双氧水加热至回收进行反应，反应产物经沉降、过滤、浓缩、结晶、干燥即得产品。

2.50g氧化锌加至300mL 20%醋酸溶液中，搅拌下加热至75～80℃，过滤滤去未溶的氧化锌。在滤液中加入8～10mL 3%过氧化氢，加热至沸。再滴入2%醋酸钡溶液，直至溶液中含有微量的SO₄^2-为止。过滤，往滤液中加入5g新制备的碳酸锌，煮沸5min后，再在水浴上加热40～50min。过滤，滤液中补充适量醋酸至略有醋酸时，冷却，抽滤出结晶，于室温下干燥。所得产品为化学纯成品。

3.用水将500g碳酸锌调成浆糊状，加入醋酸至反应后溶液中仍留有少量碳酸锌。滤去碳酸锌，在滤液中再加入30mL醋酸，浓缩滤液，冷却，抽滤出结晶，放在低温烘箱内干燥，产量600g。

4.　醋酸、氧化锌与双氧水加热至回流进行反应，反应产物经沉降、过滤、浓缩、结晶、干燥即得产品。
