氟硼酸钾制备

1．氟硼酸氢氧化钾法将氢氟酸和硼酸放入反应釜中，两者投料比为25∶62(重量比)，温度不超过40 ℃，反应6 h。将制得的氟硼酸送入中和罐，在搅拌和冷却下，与浓度为5 ｍｏl/L的氢氧化钾进行中和反应(至甲基橙变色为止)。析出的氟硼酸钾结晶经离心分离、洗涤、干燥后，制得氟硼酸钾成品。其反应式如下：

氟硼酸碳酸钾中和法在涂塑容器中于搅拌下用饱和的碳酸钾溶液中和氟硼酸，至甲基橙变色为止。析出的氟硼酸钾经离心分离、洗涤、干燥后，制得氟硼酸钾成品。其反应式如下：

2.氟硼酸钾的制取方法有氟硼酸用碳酸钾中和法；也可用硼酸或硼砂与氢氟酸作用先制取氟硼酸，再与氢氧化钾反应而得。还有氟硅酸法是将氨水加入氟硅酸钾中，然后与硼酸及盐酸反应而得；也可用氟硅酸与硼酸作用，先制得氟硼酸再用碳酸钾或氢氧化钾中和而得。也有将氟硅酸钾溶液先用氨水或氢氧化钾脱硅再同硼酸作用制取。下面是氢氟酸、硼酸、氢氧化钾法制取氟硼酸钾的方法。将氢氟酸(40%)放入氟化釜中，在搅拌下，缓慢加入硼酸。氢氟酸和硼酸的配料比为25∶6.2(质量比)。控制反应温度不超过40℃，加完硼酸后，放置6h。将制得的氟硼酸送入中和罐中，在搅拌和冷却下，缓缓加入浓度为5mol/L的氢氧化钾溶液，中和至甲基橙指示剂变色为止。析出的氟硼酸钾结晶，经离心分离，洗涤，干燥后，即得成品。分离出的母液再用于配制氢氧化钾溶液；或蒸浓后，重新冷却结晶提取产品。
