氯化钴,六水制备

1.金属钴法将盐酸加人反应器中，再逐渐加入金属钴，使其溶解并加热至80℃进行反应，并视金属钴溶解情况适当地加入硝酸，把生成的氯化钴溶液用过氧化氢净化除铁，必要时加入碳酸钠或氨水调节，以保证净化完全。经净化后的氯化钴溶液用盐酸调节至Ph2～3。经过滤、蒸发至沸腾、冷却结晶、离心分离、干燥，制得氯化钴成品。其反应方程式如下：

2.含钴废料法将各种含钴废料(下脚料)，经硝酸、盐酸、硫酸溶解，加人硫化钠转化成NiS·CoS。经通入空气氧化得到NiS()4·(30S()4，加人烧碱，通入氯气，分离得到氢氧化钴和硫酸镍溶液，将氢氧化钴加入盐酸进行反应生成氯化钴，过滤后水洗，得到粗制氯化钻，加入过氧化氢精制，再经蒸发浓缩、冷却结晶、离心分离、干燥，制得氯化钴成品。其反应方程式如下：

3.氯化钴的生产采用金属钴法和含钴废料法。工业上一般采用金属加工和以电子工业的含钴废料为原料，用混酸（盐酸和硝酸）溶解而得。
将盐酸加入反应器，再投入含钴废料于80℃下进行反应，并视金属钴溶解情况适当加入硝酸。氯化钴溶液用过氧化氢净化除铁，如溶液PH<5，则加入碳酸钠或氨水，以保证净化完全。净化后的氯化钴溶液用演算调节PH至2-3，经过滤、蒸发、结晶、分离得成品 4.三氧化二钴与盐酸反应生成氯化钴。在1L分析纯的浓盐酸(比重为119)中加入400mL水，在搅拌下慢慢加入120g Co2O3(无镍试剂)，将混合物放在水浴上加热，并分多次慢慢再加入230g Co2O3。将所得溶液过滤，向滤液中加入10mL HCl后进行蒸发浓缩，直至溶液表面有较厚的结晶膜时开始冷却。将析出的氯化钴结晶弄碎后用100mL水洗涤，在布氏漏斗上抽干，最后摊平在玻璃板上于35～45℃的温度下干燥，直至成为干燥松散的结晶为止。 5. 将份工业品六水合氯化钴和1份工业品氯化铵溶解在4份水中，加入3份相对密度为0.91的氢氧化铵，并往溶液中通入空气6～8h然后加入1份碳酸铵，溶解后重新通入空气6～8h，再将溶液慢慢加热至90℃。将溶液蒸发，添加相对密度为1.19的盐酸至石蕊呈强酸性，重新蒸发，静置过夜，析出物过滤，用分析纯稀盐酸（1∶ 4）洗涤2次，于30～45℃干燥10～12h，得分析纯成品。母液回收利用也可制取分析纯成品。母液回收利用也可制取分析纯成品。 6. 将金属钴和水加入反应器中，加热至60～70℃，再逐渐加入相对密度为1.40工业硝酸使其溶解并反应：反应结束后，加入碳酸钴调节溶液至中性并沉淀出铁。然后加热至60～70℃，保温2～3h，过滤后用等体积水稀释。将热的稀释液在不断搅拌下缓缓加到2%～5%的热氢氧化铵溶液中，至ph＝9～10，分出母液，往沉淀中加2%～5%的氢氧化铵和硝酸钴（二者量相同），分出母液（重复四遍）。将沉淀倾析洗涤2～3次，过滤，用水洗至中性，迅速沉淀并过滤。将相对密度为1.19的盐酸加到上述新鲜氢氧化钴溶液中进行反应：过滤后，蒸发溶液至相对密度为1.46～1.47，冷却结晶，用少量水洗涤，滤干，于35～45℃下干燥，即得成品六水合氯化钴。
