氯化镁,六水制备

1.海水浓缩析出氯化钠结晶后的苦卤，经提取氯化钾和溴后浓缩可制成卤片，相对密度1.7059(15.5℃)，主要成分：MgC12 46.8%，CaCl2 3.42%，NaCl 0.36%，CaSO4 0.43%。然后经真空除溴后，常压蒸发至140℃，除去杂质后，冷却即有六水氯化镁针状结晶析出，分离后再经重结晶得成品。
或将氧化镁或碳酸镁溶解于盐酸也可制得氯化镁。
2.制溟后的含氯化镁母液经蒸发浓缩(温度控制在165～170℃)，然后将浓缩液冷却结晶、分离，制得氯化镁成品。
3.将菱镁矿（或氧化镁、碳酸镁）加入水中。混合后缓缓加入盐酸。反应完全后，在溶液中加入硫酸和饱和硫化氢水溶液。静置、过滤，将滤液在80～90℃时加热，使滤液浓缩至相对密度1.33～1.35。再过滤、冷却、抽滤得氯化镁。 4.将市售的MgCl2·6H2O溶于水，通入H2S形成饱和溶液，加入少量氨水，保持温热放置数日，小心将上面清液倾出。为了沉淀Ca2+加入少量纯草酸铵，放置沉降，倾析清液，再向清液中加入草酸铵，较长时间放置之后没有沉淀产生，说明Ca2+已除净。

蒸发澄清液并灼烧析出的盐，这样可得到MgO和氯氧化镁的混合物，将其在布氏漏斗上过滤洗涤60h,至洗涤水中不含Na+和K+。用蒸馏过的盐酸溶解洗净的混合物。将溶液蒸发浓缩，冷却后即可析出MgCl2·6H2O(MgCl2·6H2O析出的温度范围-3～116℃)。

如果Na+和K+不能除尽，可多次重复上述操作，直至检验不出痕量的Na+和K+。

上述精制操作宜在石英器皿中进行，用电炉加热，不用煤气灯以免硫污染产品。

5.制溴后的含氯化镁母液经蒸发浓缩（温度控制在165～170℃），然后将浓缩液冷却结晶、分离，制得氯化镁成品。

6.将200kg工业氯化镁和200～250kg纯水混合加热并溶解（要求溶液相对密度为1.2），待溶液冷到50～60℃时，边搅拌边缓慢加入1～1.5kg工业品双氧水，静置4h，过滤得无色透明的滤液（无荧光），加热沸腾浓缩至相对密度为1.45左右，用水冷却结晶，同时不断搅拌，以防颗粒太大。结晶完成后，甩干，即得试剂六水合氯化镁。
