The preparation of alkali metal chlorates by electrolysis of the corresponding chlorides has been studied by various authors [1]. However, reports of electrochemical methods for preparing alkaline earth metal chlorates are scarce, even though their salts have some specialty applications [2, 3]. In the case of the electrolysis of magnesium chloride, the precipitation of the magnesium hydroxide due to its low solubility is problematic, leading to a loss in current efficiency. Further, heavy deposits of magnesium hydroxide form on the cathode with consequently increased cell voltage. This difficulty has been obviated using a rotating stainless steel cathode which minimises hydroxide precipitation. A titanium coated metal oxide anode was used for the oxidation of magnesium chloride to magnesium chlorate. This paper presents results for the preparation of magnesium chlorate from magnesium chloride [4].

氯化镁电解制备氯酸镁

多位作者已经研究了通过电解相应氯化物制备碱金属氯酸盐[1]。然而，关于制备碱土金属氯酸盐的电化学方法的报道很少，尽管它们的盐有一些特殊的应用 [2, 3]。在电解氯化镁的情况下，氢氧化镁由于溶解度低而沉淀是有问题的，导致电流效率的损失。此外，阴极上会形成大量氢氧化镁沉积物，从而增加电池电压。使用可最大限度减少氢氧化物沉淀的旋转不锈钢阴极已消除了这一困难。钛涂层金属氧化物阳极用于将氯化镁氧化成氯酸镁。
