KHF2 (potassium hydrogen fluoride)
Known as the two potassium hydrogen fluoride; acid potassium fluoride; hydrogen fluoride and potassium
The physical properties of colorless tetragonal (α) or cubic (β)crystallization.
The slightly sour smell. Double-crystal compounds.
Α-type below195 ℃ , 195 ~ 239 ° C for the β-type.
The relative density of 2.37. The melting point of about 225 ° C (decomposition).
Soluble in water, soluble in potassium acetate, insoluble in ethanol.The acidic aqueous solution.
In dry air, regardless of the liberation of hydrogen fluoride, in themoist air to absorb water and release hydrogen fluoride.
Heated to 310 ° C, the escape of hydrogen fluoride, hydrogen fluoride to 400 ° C vapor pressure up to 0.101325MPa (1atm).
Activity of the molten potassium hydrogen fluoride is potassium fluoride.
Toxic. Corrosive.
KHF2 is used in the manufacture of anhydrous hydrogen fluoride,potassium fluoride pure optical glass element fluorine is also used as the etchant of glass, welding flux, wood preservatives, etc.
Toxic toxic protection, the maximum allowable concentration2.5mg/m3.
Corrosive to the skin, mucous membrane irritation. Thermal decomposition will generate hydrogen fluoride. Operation must wear protective equipment, avoid contact with the skin, others seehydrogen fluoride.
Packing and storage: iron drum lined with two layers of polyethyleneplastic bags, barrel, net weight45kg . The packaging should be clearly
marked "drugs"
sign.
Inorganic drugs, the IMDG Code: 83020.
KHF2 should be stored in a cool, ventilated, dry coffers. The packagingmust be complete. Storage should take strict precautions againstmoisture. Non-food items during storage or shipment.
During transport to prevent the rain and sun.
