氯化亚锡制备

1.由锡花或锡与浓盐酸反应，反应产物经浓缩、过滤、冷却、结晶、离心分离而制得二水合氯化亚锡，再经干燥脱水、粉碎即得成品。盐酸法先将金属锡熔融，然后泼入冷水，激成锡花。再将盐酸和锡花按一定配比加入反应器中进行反应，待溶液浓度达到40°Ｂé左右时，放入搪瓷蒸发器中进行浓缩。首先向蒸发器中加入锡花，通入蒸汽加热，使盐酸与锡继续反应，当溶液浓度增加到73～77°Ｂé时，趁热过滤，再经冷却结晶、离心分离，制得氯化亚锡成品。其反应式： 2.将70g锡粒放入铂皿中，若无合适的铂皿，也可用瓷皿，在皿中放入任何一种铂制物件，加入180mL盐酸（相对密度1.19），煮沸至锡完全溶解。过滤溶液，并蒸发（最好在真空中）滤液至浓缩液冷却后能析出结晶为止。在冰水浴中冷却使之结晶。过滤，晶体在过滤漏斗上淋尽母液，将结晶放入磨口瓶中。母液再经蒸发浓缩还可得到一部分相当纯的产品。产量110～120g，产率83%～90%。 3. 采用盐酸法。先将金属锡熔融，然后泼入冷水，激成锡花。再将盐酸和锡花按一定配比加入反应器中进行反应，待溶液浓度达到40°Ｂé左右时，放入搪瓷蒸发器中进行浓缩。首先向蒸发器中加入锡花，通入蒸汽加热，使盐酸与锡继续反应，当溶液浓度增加到73～77°Ｂé时，趁热过滤，再经冷却结晶、离心分离，制得氯化亚锡成品。其反应式如下。
