Potassium hydrogen fluoride Usage And Synthesis

Description	Potassium hydrogen fluoride is used as an etchant to etch glass surface and it is used in the cleaning products. It is used as a fluorinating agent for fluorinated organic compounds, which could be applied as finishing agent for fabrics, components of extinguishing agents, electroplating bathes, lubricating oils, oxygen carriers in blood substitutes. For example, potassium hydrogen fluoride is used as fluorinating agent for ring opening of epoxides and cyclopropanes and in the synthesis of trifluoroborates from various organoborons. It may also serve as a fluoride ion source for the nucleophilic ring-opening reaction of epoxide.

Chemical Properties	WHITE TO LIGHT GREY CRYSTALS OR CRYSTALLINE POWDER
Uses	In the preparation of pure potassium fluoride; as an electrolyte in the manufacture of fluorine; frosting glass; treating coal to prevent slag formation; flux for silver solders; catalyst in the alkylation of benzene with olefins.
General Description	Colorless crystals, corrosive to tissues, etches glass.
Air & Water Reactions	Water soluble giving strongly acidic solutions.
Reactivity Profile	Acidic salts, such as Potassium hydrogen fluoride, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Health Hazard	TOXIC; 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 Hazard	Non-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.
