碘酸钾制备

1.氯酸钾氧化法：将碘和氯酸钾按配料比为12：KCI3=21：20和水加入反应器中，用硝酸调节溶液pHl～2。在搅拌下于80～90℃使溶液沸腾1h反应完全并逐出氯气。将溶液冷却至室温，析出碘酸氢钾结晶，经过滤，将结晶用热水加热溶解后，加入苛性钾中和至溶液Ph值为10，再经冷却结晶、过滤、干燥，制得碘酸钾成品。其反应方程式如下：

2.用KOH溶液中和酸式盐KIO3·HIO3可制得碘酸钾。将200g KIO3·HIO3溶解于1100mL水。所得溶液加热到70～80℃，缓慢加入30％KOH溶液，直到溶液对石蕊呈碱性反应(约需加碱65～70mL)。将溶液过滤后静置过夜。析出的KIO3结晶用布氏漏斗抽滤，用40mL水洗涤。往母液中添加100g KIO3·HIO3，并重新加入30％KOH溶液，直到溶液呈碱性(约需碱30～35mL)。然后过滤，结晶。将第二次结晶液(约1L)蒸发到形成结晶薄膜时，静置结晶。将三次所得KIO3结晶合并约240g。所得产品可在热水中重结晶纯制。经两次重结晶后得产品175g(产率54％)。

3.氯酸钾氧化法：在稀硝酸介质中，氯酸钾直接氧化碘而得。

4.焙烧氧化法：将碘化钾在氧气的高压下，加热至600℃，可直接制得碘酸钾。
