氟化氢钾 (CAS No.7789-29-9)
- 物化性质
- 熔点约238°C（分解），易溶于水，不溶于乙醇，水溶液呈酸性。在干燥空气中不分解放出氟化氢，在潮湿空气中吸收水分并放出氟化氢。加热至310°C时开始有氟化氢逸出，至400°C时氟化氢蒸气压可达0.101325 MPa（1 atm）。熔融氟化氢钾的活性比氟化钾、氟化钠大。有毒。
- 技术参数
- 纯度≥98% 熔点约238°C（分解） 易溶于水，不溶于乙醇 水溶液呈酸性

Product Name:Potassium bifluoride
English Name:Potassium bifluoride
CAS No.:7789-29-9
Aliases:Potassium hydrogen difluoride, Acid potassium fluoride
Molecular Formula:KHF2
Physical Properties:Melting point approximately 238°C (decomposes). Readily soluble in water, insoluble in ethanol, aqueous solution is acidic. Does not release hydrogen fluoride in dry air, but absorbs moisture and releases hydrogen fluoride in humid air. When heated to 310°C, hydrogen fluoride begins to evolve; at 400°C, the vapor pressure of hydrogen fluoride reaches 0.101325 MPa (1 atm). The activity of molten potassium bifluoride is greater than that of potassium fluoride or sodium fluoride. Toxic.
Uses:Used to produce elemental fluorine by electrolysis; also used in the manufacture of anhydrous hydrogen fluoride, pure potassium fluoride, optical glass, and elemental fluorine, as well as a glass etching agent, soldering flux, and wood preservative.
Technical Specifications:
Purity ≥ 98%
Melting point approximately 238°C (decomposes)
Readily soluble in water, insoluble in ethanol
Aqueous solution is acidic
Packaging: 25 kg/bag
