六水合硝酸钴制备

1.在氢氧化钴或磷酸钴中加入硝酸，反应后重结晶而得。或用金属钴与硝酸进行反应，加入磷酸钴，调节pH值，过滤除去氢氧化铁，再用硝酸酸化，蒸发结晶，即可制得硝酸钴。

合成法：将30%～32％硝酸加入带搅拌的耐酸反应器中，在搅拌下缓慢加入金属钴粒进行反应，待反应接近完全后，通入蒸汽加热赶出氧化氮气体，将溶液送入澄清器，在搅拌下加入碳酸钴调节溶液至pH 5左右，在80～90℃保温1天，趁热过滤除去氢氧化铁沉淀，滤液用硝酸酸化至pH＞1，再蒸发浓缩至溶液的相对密度1.6～1.7，经冷却结晶、离心分离，制得硝酸钴成品。其反应式如下：

反应过程中有氧化氮气体逸出，有毒，处理方法参见硝酸钠生产的吸收法。

2.将水合三氧化钴或碳酸钴溶于稀硝酸中，过滤，减压浓缩滤液，冷却后即得到六水合硝酸钴(Ⅱ)。

3.将密度为1.4的试剂硝酸以7∶ 10的体积比溶于热水中，在通风条件下分次少量加入三氧化二钴试剂进行反应：

反应后期分批加入少量福尔马林，溶液逐渐透明。加热30min后趁热过滤。滤液蒸发至出现结晶薄膜，冷却至5～10℃结晶，吸滤，结晶用少量水洗涤后，逐渐升温至40～50℃，干燥到结晶不粘玻棒即可。
母液经酸化后，按上述方法处理，可得到一定量纯品硝酸钴。

4.将密度为1.40的硝酸在搅拌下缓慢加到试剂氢氧化钴中，直到对刚果红呈弱酸性反应：

将溶液加热到70～80℃，在搅拌下加入少量30%的过氧化氢，趁热过滤，室温下静置结晶，吸滤后即得试剂硝酸钴。
