溴化汞制备
1.将相对密度为1.40的硝酸溶解在水中，然后慢慢加入黄色氧化汞。
待溶液澄清后进行过滤，检验滤液中Hg2+离子含量合格后，加入事先备好的含量为60%左右的溴化钠水溶液进行反应。
待修化工沉淀完全后，抽虑分离出沉淀物，用水洗涤2-3次，以除去NO3-离子，用二苯胺试验合格后，将结晶置于滤纸上于60-70ºC干燥，得成品溴化汞。
2.在通风良好的环境中，将1份质量的汞放入烧瓶中，并向其中注入12份质量的水，然后把混合物加热至40℃，在搅拌下，向混合物中滴加8份质量的溴。当反应结束后，将烧瓶中溶液加热至沸腾，以除去过量的溴，并趁热快速过滤溶液。随后迅速将溶液置于冰浴中进行快速结晶；抽滤出HgBr2结晶后，用少量冰水洗涤，并在尽可能低的温度下进行干燥。最后把干燥了的产品置于瓷蒸发皿上，用盛满冷水的培养皿盖在上面，在220～250℃下进行升华提纯。如果要得到很纯的HgBr2则可进行多次升华提纯。
