氯化铍制备
1.将氧化铍加入盛有适量蒸馏水的反应器中，在搅拌下缓慢加入盐酸进行反应，把反应溶液蒸发浓缩，冷却结晶，离心分离，干燥，制得氯化铍成品。其反应式如下：
2.氯化铍的制备装置
1—玻璃管；2—储槽；3—排气管将碱式碳酸铍在800℃下加热制成氧化铍。取氧化铍150g与75g糖炭用少量水混合，制成球状物。将其置于石英管内，加热至300℃，除尽水分。然后放在电炉中。见图Ⅱ2的装置所示。
从管口1处通入氯气10h，保持每分钟120个气泡的速度，同时加热至900℃,所生成的氯化铍即凝结在石英管的冷却部分。
将制得的氯化铍收集在储槽2中。将过量的氯气与二氧化碳、一氧化碳从排气管3排出。要妥善处理排出气体。
