Potassium fluoride Usage And Synthesis
Chemical PropertiesPotassium fluoride, KF, is a colorless, deliquescent crystalline solid that has a melting point of 846 °C(1550 °F). Potassium fluoride has a salty taste and is poisonous. It is soluble in water,but insoluble in alcohol. Potassium fluoride is used in etching glass,preservatives, and insecticides.
Physical and Chemical PropertiesPotassium fluoride is basis raw material of manufacturing fluoride, chemical formula is KF. Molecular weight is 58.10. It is colorless cubic crystal or white powder. It is poisonous! It is deliquescent. Taste is salty. Specific gravity is 2.48. Melting point is 858℃. Boiling point is 1505℃. It is soluble in water. It was dissolved in hydrofluoric acid and ammonia. It is insoluble in ethanol, acetone. Aqueous solution is alkaline and it can corrode glass and porcelain. It can cause irritation for human skin, mucous membrane and eye. When belows 40.2℃, it can crystallize in an aqueous solution to give dihydrate KF·2H2O, which is monoclinic, it is self-dissolved crystalline water at 41℃. It can be obtained by the thermal decomposition of potassium hydrogen fluoride or potassium carbonate (or potassium hydroxide) and hydrofluoric acid (40% or anhydrous). It can be used for glass engraving, food preservation, it can be also used as welding flux, fluoride, pesticides,etc.

Chemical PropertiesWhite, crystalline, deliquescent powder; sharp saline taste.Soluble in water and hydrogen fluoride, insoluble in alcohol.
Chemical PropertiesPotassium fluoride is a white crystalline solid.
Uses
Industry Application Role/benefit
Organic synthesis Preparation of various organic fluoride Fluorinating agent/replaces other halide ions like chlorine, bromine etc.
Chemical manufacture Manufacture of polyurethanes and alkyl benzenes Catalyst/promote the reaction rate
Manufacture of pesticides and insecticides Fluorinating agent; ingredient
Manufacture of potassium bifluoride Raw material
Metallurgy Soldering Soldering fluxes/help to remove oxide film
Tin plating Plating composition/source of fluoride
Glass Etching of glass Glass etching composition; source of fluoride
Others Food and wood preservative Source of fluoride
Absorption of hf and moisture Adsorbent/anhydrous potassium fluoride has hydroscopicity
Complexometric titration of tantalum Masking agent
Extraction of tantalum from ore Precipitator/reacts with fluorotantalic acid to precipitate potassium fluorotantalate
 
Reactivity ProfilePotassium fluoride reacts with acids to evolve corrosive and toxic hydrogen fluoride. Aqueous solutions corrode glass and consequently are prepared and stored in polyethylene containers. The pure solid may be stored in glass containers. Reacts violently with (Pt + BrF3). [NTP 1992].
HazardToxic by ingestion and inhalation, strong irritant to tissue.
Health HazardTOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Safety ProfilePoison by ingestion and intraperitoneal routes. Moderately toxic by subcutaneous route. Experimental teratogenic effects. A corrosive irritant to the eyes, skin, and mucous membranes. Mutation data reported. A very reactive material. When heated to decomposition it emits toxic fumes of K2O and F-. Used in etchmg glass, as a presewative, as an insecticide, and in organic synthesis. See also FLUORIDES and HYDROFLUORIC ACID.
Potential ExposurePotassium fluoride is used in etching glass; as a preservative and insecticide.
First aidMove victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respira- tion with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with run- ning water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical obser- vation is recommended for 24?48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
