硝酸钡制备方法及用途

制备方法

1.硝酸-碳酸钡法碳酸钡与硝酸进行反应，加入适量烧碱除去三价铁离子，再将溶液加热至95℃以上澄清，清液经冷却结晶，过滤(母液循环)、在250℃下干燥、粉碎，即得硝酸钡成品。其反应方程式如下：2.硝酸盐法以硝酸铵和氯化钡为原料进行反应，再将溶液冷却到25℃结晶，经过滤、洗涤、干燥，即得硝酸钡成品。其反应方程式如下: 3.将245g的BaCl2·H2O溶于500mL热水中，再与85g(1mol)的硝酸钠溶于85mL热水中的溶液相混合。冷却后析出的结晶再进行重结晶。4.取经过研细的硫酸钡47g(02mol)与12g木炭充分混合，置于坩埚中，表面再盖以少量木炭粉。于1000℃下加热2h。冷却后将其粉碎，放入100mL 8mol/L硝酸中，边加热边搅拌，过滤，将滤液加热浓缩直至析出结晶。冷却后分出晶体，在60℃干燥箱中干燥，得到产品约40g(收率为77%)。5.取50kg工业品氯化钡放入耐酸缸中，并加水浸没，搅拌均匀后，静置一昼夜，过滤甩干，将甩干的氯化钡加水并通蒸汽加热至密度约为1.23（ 50℃）。在耐酸缸内投入55kg的发烟硝酸（工品），边搅拌边将冷却到25℃的氯化钡溶液慢慢倒入硝酸中，生成硝酸钡沉淀：待反应完全后吸出母液。将洁净的经蒸馏水加入硝酸钡进行洗涤搅拌，静置使其完全沉淀，吸去上层清液，重复洗涤三次，然后甩干，再在离心机内洗涤到Cl-含量达到要求后甩干。按每37.5kg硝酸钡加入蒸馏水120ml，溶成密度为1.16（95℃）的溶液。滤去不溶物，将澄清液在缸中冷却至20℃，结晶完全后甩干，结晶平铺于搪瓷盘中，在100～110℃的烘箱内烘干。母液可再蒸发，冷却结晶，若犆犾－离子含量不合格，用蒸馏水洗涤至合格。6.将50g分析纯硝酸钡加到200ml蒸馏水中，加热溶解后，加入5g活性炭，煮沸一会儿，过滤，冷却结晶，抽滤后在100℃下干燥，即得优级纯硝酸钡（母液蒸发结晶，可制得一定量的较低纯度的硝酸钡）。7.将1kg分析纯硝酸钡加电导水煮沸，使之完全溶解（如溶解不完，继续加水）。加入2ml5%的高纯硫酸，快速搅拌，待沉淀（硫酸钡和少量硫酸锶）完全后过滤。滤液中，加少量碳酸钡和氢氧化钡，过滤、滤液浓缩、结晶，用电导水溶解，重结晶两次，最后，将结晶置于100℃烘箱内干燥2h，得光谱纯硝酸钡。
