• 电解法生产氯酸钾:电解法生产氯酸钾是用精制饱和盐水在电解槽内通直流电，电解后可得NaClO3溶液，将此溶液与氯化钾(KCl)进行复分解反应，便得到氯酸钾溶液。然后进行冷却结晶、固液分离、精制、干燥和粉碎等工序，得氯酸钾。 1. 盐水精制 将食盐溶成饱和盐水，并加入NaOH、Na2CO3和BaCl2，除掉Ca2+、Mg2+等杂质。精制的盐水用盐酸中和过量的碱，调节pH=6～7，并加入红矾钠，使精制盐水中含Na2Cr2O7为1.5～2.0g/L，防止ClO-的还原。 2. 电解 精制后的盐水中含NaCl，以石墨(陶基二氧化铅,TiRu金属) 作阳极，以普通软钢作阴极，极间距离为2～4mm，在温度为40～90℃、pH 为6.7的条件下进行电解。当电解液中NaClO3含量达到400g/L时，停止电解，将电解液送至下一工序。电解工序反应如下：Nacl+3H2O--NaclO3+3H2。 3. 除溴和次氯酸根 将电解完成液加盐酸酸化并加热至110℃，在除溴塔内用空气将溴和次氯酸根吹除，减少产品中的溴酸盐，避免ClO-对设备的腐蚀。 4. 复分解反应 除溴后的氯酸钠溶液，加入略低于理论量的KCl，在60℃温度下搅拌反应，生成KClO3。 5. 冷却结晶 复分解反应后的溶液，进行冷却结晶，便得到粗品KClO3。冷却温度为45℃左右。母液经蒸发浓缩后析出NaCl，送化盐工序循环使用。
