Experiments proved that potassium borofluoride production process by waste acid was totally feasible.The process should firstly use the stoichiometric boric acid to react with 30%(mass fraction) ...

• 经过试验证明先用化学计量的硼酸与30%25(质量分数)氢氧化钾反应制成偏硼酸钾溶液,偏硼酸钾溶液再与废酸反应制得氟硼酸钾的工艺是完全可行的,实施后每年可回收氢氟酸120t(以100%25计),具有很大的经济效益。
