三氯化铁

三氯化铁用途

【用途一】
主要用作水处理剂，还用作媒染剂、催化剂、氯化剂，并用于制造其他铁盐等主要用于净水，也用于印刷制板、颜料、染料及药物等
【用途二】
用作分析试剂及电子器件腐蚀剂
【用途三】
用作分析试剂和薄层色层显色剂
【用途四】
用作饮水的净水剂和废水的处理净化沉淀剂。用于印刷电路作刻蚀剂。
【用途五】
主要用作饮水的净水剂和废水的处理净化沉淀剂。印染工业用作靛蓝染料染色时的氧化剂和印染媒染剂。有机合成二氯乙烷等生产的催化剂。银矿和铜矿的氯化浸提剂。照相和印刷制版的刻蚀剂。制造磷酸铁等铁盐、医药、颜料和墨水的原料。在建筑混凝土中渗入其溶液后能增加建筑物强度、抗腐蚀性和防止渗水。用于电子工业线路板及荧光数字筒生产。生产肥皂的废液回收甘油时的凝聚剂。
【用途六】
营养增补剂(铁质强化剂)。用于婴儿奶粉、离乳食品等。
能与乳中的β-球蛋白结合形成蛋白铁，体内容易吸收。因酸性较强，不宜直接添加，通常与乳清作用制成乳清铁后添加，调整至1g乳清铁约含铁4mg。在上述食品中的乳清铁添加量1.0%～1.5%。
铁一般会促进食品中脂肪氧化。与蛋白质结合的乳清铁则不会促进氧化。
【用途七】
主要用作工业水处理、照相和印刷制版的腐蚀剂、有机合成工业的催化剂、氧化剂,染料工业的氧化剂和媒染剂制造其它铁盐、颜料、墨水、医药的原料等高纯级(99.99%)在氢作用下和金属卤化物气相共还原产生可分离的金属间化合物,该化合物具有导热导电、磁感应和抗氧化特性。

三氯化铁制备

【方法一】
盐酸法将盐酸和铁屑加入反应器中进行反应，生成二氯化铁溶液，经澄清，把氯气通人清液进行氯化反应，生成三氯化铁溶液，再经澄清，制得三氯化铁溶液成品。其
Fe+2HCl→FeCl2+H2
2FeC12+C12→2FeC13
一步氯化法将氯气直接通人浸泡铁屑的水中进行氯化反应，生成三氯化铁溶液，经澄清，制得液体三氯化铁成品。其
2Fe+3C12→2FeC13
【方法二】
在由铁屑与盐酸制得的氯化亚铁溶液内，通入氯气，转变成氯化铁溶液。再加铁还原成氯化亚铁溶液，重新通入氯气制成氯化铁溶液。重复这一操作至氯化铁的浓度提高到约60%，放冷析出晶体(含水物)。
【方法三】
铁屑氯化法将废铁屑放人钢制立式反应炉内进行氯化。反应炉上部为预热段，内衬耐火材料；下部为反应段，有水冷夹套。废铁屑(丝)从顶部加入，与逆流而上的氯气在下部反应段进行反应。生成的三氯化铁蒸气和尾气由顶部排出，进人冷凝捕集器中冷凝为固体结晶，经搅拌器从冷凝捕集器壁上刮下，制得无水三氯化铁成品。其
2Fe+3C12→2FeC13
尾气中含有少量未反应的游离氯和三氯化铁，用氯化亚铁溶液吸收氯气，得到三氯化铁溶液。生产操作中，因三氯化铁蒸气与空气中水分接触后强烈发热，并放出盐酸气，因此管道和设备要密封良好，整个系统在负压下操作。
