铁氰化钾制备

1.由黄血盐钾作原料，采用氯气氧化法制得，或用电解法使黄血盐钾发生氧化还原反应制得。氯气氧化法黄血盐钾热溶液在氯气作用下，于60～65℃左右进行氧化生成赤血盐钾。控制反应料液ph值为6～7时，停止通入氯气，再加入高锰酸钾饱和溶液，并以硫酸高铁铵检验为棕红色为止。用盐酸调节物料的酸碱度，使ph值为7～8，反应后物料经沉降、过滤、真空蒸发至溶液相对密度12时，再经冷却结晶、离心分离、干燥，得赤血盐钾成品。其反应式如下：

2. 将工业铁氰化钾溶于水中。过滤，冷却，吸滤所析出的结晶，洗涤。在室温下干燥，得纯品铁氰化钾。 3. 制法将工业品六氰合铁（ Ⅲ）酸钾加到水中（350ml水中加130～135 g），搅拌，加热（不超过70℃），待全部溶解后，过滤，冷却结晶，离心甩干，用少量水洗涤，在室温下干燥，即得分析纯成品。 4. 电解法　将黄血盐钾的饱和溶液在60℃以下进行电解，使黄血盐钾发生自偶氧化还原反应生成赤血盐钾及副产品氢氧化钾。待电解液中铁氰化钾含量达320g/L时开始冷却结晶，浓度降至280g/L后进行分离、干燥，制得赤血盐钾成品。其反应式如下：
