次氯酸钠制备
1.液碱氯化法:将一定量的液碱加入适量的水,配成30%以下氢氧化钠溶液,在35℃以下通入氯气进行反应,待反应溶液中次氯酸钠含量达到一定浓度时,制得次氯酸钠成品。其
2.向冷氢氧化钠溶液中通入氯气。在反应器中将500g NaOH溶于500mL水,将此溶液与2kg碎冰混合。用致冷剂尽量冷却混合物(温度应低于-10℃),在冷却下减压通入氯气直至溶液增重800g为止。所得NaClO溶液中等浓度,可在阴暗冷处长期保存。
3.用漂白粉和碳酸钠反应制备。把100g含35%~36%有效氯的漂白粉与170mL水混合均匀搅拌15min。在搅拌下向此溶液中加入70g Na2CO3溶于170mL水的溶液。反应物最初变稠,然后变稀,过滤除去CaCO3沉淀得320mLNaClO溶液。有效氯71~100g/L。
4.将氯气通入氢氧化钠溶液中即可制得次氯酸钠的饱和溶液,含量为5.25%。
