氯化钡,二水制备

1.盐酸法将硫化钡溶液(制备参见硫化钡)与盐酸进行反应，再经脱硫、中和、蒸发、冷却结晶、离心分离、干燥．制得二水氯化钡成品。其反应方程式如下：

2.氯化钙法将重晶石与煤粉和氯化钙水溶液进行反应，浸取后加入盐酸进行脱硫，再经蒸发浓缩、冷却结晶、离心脱水、干燥，即得二水氯化钡成品。此法亦可制得无水氧化钡。其反应方程式如下：

3.氯化法用水浸取硫化钡熔体后，再将所得到的170 g/L硫化钡溶液在85～90℃下进行氯化，制得氯化钡成品。其反应方程式如下：

4.毒重石-盐酸法将毒重石粉加入盛有水的反应器中，在搅拌下加人盐酸于70℃左右进行反应，过滤，热水洗涤，滤液进行蒸发浓缩，冷却结晶，离心分离．制得二水氯化钡成品。其反应方程式如下：

5.以工业品二水氯化钡为原料，将其溶于热水中制成25%的水溶液，根据杂质含量，添加3%的氢氧化钡溶液和硫化铵溶液。所得混合物在20～30min内加热到80～90℃，静置过滤，将滤液蒸发到相对密度为1.33（30℃）时进行冷却，结晶经抽滤，用少量冷水洗涤后在室温下干燥，成品为析纯氯化钡。母液可循环使用。

6.将1.2kg分析纯氯化钡溶于3600mL电导水中，搅拌使之完全溶解。在溶液中加入50mL5%的高纯氯化钡（或少量氧化钡）。静置3h，过滤，取5mL滤液于试管内，加2滴硫化铵溶液，如有沉淀产生，根据其杂质的量确定所需硫化铵的加入量。将溶液加热20min，冷却后过滤，滤液加热蒸发至相对密度为1.33（30℃），冷却结晶，抽滤后用少量电导水洗涤，在低60℃下干燥，可得650g光谱纯氯化钡。
