制备

1.电解法

在阳离子交换膜隔成的三室型电解槽中，将二氧化氯气体（含量15%左右，ClO₂︰Cl₂的摩尔比不低于15︰1）通入阴极室，溶于溶液中，在30℃左右从阴极获得亚氯酸根，阳极室中不断通入氯化钠溶液，氯离子放出电子，变成氯气逸出。钠离子则在直流电场作用下，穿过阳极膜进入阴极室与亚氯酸根结合为亚氯酸钠。溶液含量17%～23%，除去微量二氯化氯后，喷雾干燥即得成品。

其反应式如下：

2.过氧化氢法

用空气把原料二氧化氯稀释至10%左右，进入鼓泡式吸收器，再通过蛇管冷凝吕，向吸收器送入含量为30%的过氧化氢，并通入NaOH液（160g/L)，在0～2℃反应。反应结束后，过滤，然后将滤液真空蒸发至350～400 g/L时，移至结晶器，在-5～-10℃下结晶，在70℃以下用空气干燥得成品。

其反应式如右：

3.由24.5g KClO3,20g草酸和21.6g H2SO4(11.8mL，相对密度1.84)与80mL水制得ClO2。把制得的ClO2通入一个盛有200mL水并用冰冷却的锥形瓶中。把橙黄色的ClO2溶液与过量的固体Ba(OH)2·8H2O,和12g 30% H2O2一起摇荡，直到溶液褪色。Ba(OH)2·8H2O较计量数过量31.6g，为了除去溶液中的CO2。抽滤，除去生成的BaCO3。滤液加热至沸，加固体Na2SO4，使过量的Ba2+都成BaSO4沉淀。抽滤除去BaSO4,把滤液在水浴上蒸至NaClO2·3H2O结晶析出。产率54％。
