摘要： Process for the preparation of a sodium paraperiodate wherein an iodine compound is converted into the sodium paraperiodate in the presence of Na.sup.+ ions by means of an alkali metal hydroxide and an alkali metal hypochlorite. The iodine compound is applied in the form of an iodine-containing mixture in which besides the iodine compound in the form of I.sub.2, iodide or iodate compounds, one or more compounds chosen from the group of chlorides, bromides, sulphates, sulphites, carbonates, bicarbonates, nitrates and dissolved organic components are also present. The invention also relates to the preparation of sodium metaperiodate and other alkali and alkali earth metal periodates, wherein the sodium paraperiodate obtained is converted into sodium periodate or into an alkali or alkali earth metal periodate by means of an acid or an alkali and alkali earth metal salt at an elevated temperature. The acid used preferably is HNO.sub.3.
摘要翻译：制备偏高碘酸钠的方法，其中碘化合物通过碱金属氢氧化物和碱金属次氯酸盐在Na +离子存在下转化成偏高碘酸钠。碘化合物以含碘混合物的形式施用，其中除碘，碘化物或碘酸盐化合物形式的碘化合物之外还有一种或多种选自氯化物，溴化物，硫酸盐，亚硫酸盐，碳酸盐，也存在碳酸氢盐，硝酸盐和溶解的有机组分。本发明还涉及偏高碘酸钠和其它碱金属和碱土金属高碘酸钠的制备，其中所得的偏高尿酸钠通过酸或碱和碱土金属转化成高碘酸钠或高碱性碱金属或碱土金属高碘酸盐盐在升高的温度。所使用的酸最好是HNO3。
