氯化钠合成路线

氯化钠下游产品
氯化钠制备
1.由海水(平均含2.4%氯化钠)引入盐田，经日晒干燥，浓缩结晶，制得粗品，粗盐中因含有杂质，在空气中较易潮解。亦可将海水，经蒸汽加温，砂滤器过滤，用离子交换膜电渗析法进行浓缩，得到盐水(含氯化钠160～180g/L)经蒸发析出盐卤石膏，离心分离，制得的氯化钠95％以上(水分2％)再经干燥可制得食盐(table salt)。还可用岩盐、盐湖盐水为原料，经日晒干燥，制得原盐。用地下盐水和井盐为原料时，通过三效或四效蒸发浓缩，析出结晶，离心分离制得。用于制造纯碱和烧碱及其他化工产品，矿石冶炼。食品工业和渔业用于盐腌，还可用作调味料的原料和精制食盐。 2.将市售精盐800g溶解于2L蒸馏水中，加入少量氢氧化钠，煮沸，放置过夜，过滤，保持滤液清洁，用冷水冷却滤液同时通入纯净的HCl气体使之饱和，氯化钠结晶即可析出。将结晶与母液离心分离。将结晶再次溶于蒸馏水中，重复以上操作。将得到的NaCl结晶放置在铂制容器中，进行干燥熔融，反复三次以除去痕量硅酸盐，再用蒸馏水溶解，过滤，滤液在铂皿中蒸发浓缩，至约2/3的NaCl析出，停止蒸发，充分冷却，离心分离出结晶，在铂皿中置于120℃烘箱干燥，并不断搅动以防结块。干燥后的细小结晶再在600～650℃高温中充分干燥，此法可得纯度为99.8%以上的精制NaCl。 3. 以海水、井盐、湖盐及矿盐为原料提取而得，精制盐则需进行多次除杂的重结晶操作而制得。 4. 取工业食盐150kg，加蒸馏水，加入5.5g工业品氯化钡，直接通蒸汽加热至全部溶解。静置。检验清液中SO

2-离子含量合格后，将清液移入另一缸内，加入27.5kg的工业品碳酸钠，充分搅拌后，再加入工业氢氧化钠溶液至ph＝10～11，直接通入蒸汽，沸 腾 后 静 置 24h以 沉 淀 除 去
Ca 2+ Mg 2+Fe 3+等杂质离子。检验这些离子合格后，过滤，在搅拌下向滤液中加入化学纯盐酸进行中和至ph=4～5。加热蒸发使晶体全部析出。离心甩干，置于烘箱内于80～100℃烘干，得试剂氯化钠。
5.加热搅拌使40g分析纯氯化钠溶解于120ml高纯水。加入2～3ml铁溶液 （7mg／ml ） ，搅拌均匀后，滴加提纯氨水至ph值为10左右。水浴加热使氢氧化铁沉淀析出，过滤。滤液放在铂皿中，低温密闭蒸发至结晶薄膜，冷却抽滤，乙醇洗涤后，在真空干燥箱内于105℃和2666Pa压力下干燥。此法得到的氯化钠经光谱定性分析仅含微量Si、AL、Mg和痕量Ca。 6. 盐田法 这是古老的制盐方法，海水受热，水分逐渐蒸发，盐的浓度逐渐升高，可以得到各种盐。当水分蒸发到90%时，食盐开始析出。 7. 电渗析法 利用电力使海水中的氯化钠浓缩。该方法是日本主要的氯化钠生产方法。 8. 冷冻法 温度降到零下18℃时海水会结冰。对制盐来说，去掉冰就等于盐田法的蒸发。温度不断降低，会结晶出不同的物质。在零下22.4℃之前将固体和海体分开，就可以得到纯净的氯化钠结晶。

现在市面上卖的盐五花八门，不但品种繁多，价钱也相差甚远，如有的食盐1元一包，有的食盐5元一包，还有的食盐一包的价钱能破十。市面上卖的食用盐，根据其种类不同价位也有较大差异，分别从1元到几十元不等，这些不同种类的食盐虽然基本成分都是氯化钠。但除此之外不同种类的食盐所含的成分还是有所差距的，如加碘盐中...
