Fluoroboric acid Usage And Synthesis

Outline	Fluoroboric acid is also known as "hydrogen fluoroboric acid," "tetrafluoroborate boron-hydrogen acid." Chemical formula is HBF4. Molecular weight is 87.81. It is transparent colorless liquid, toxic, has a strong corrosion, it can not be stored in a glass container for a long time. Boiling point is 130 ℃, while it decomposes slowly. Dissolved in water and ethanol, thermal decomposition with water to generate oxygen fluorine boric acid and boron trioxide (may be concentrated to 30%), the solution was strongly acidic, it does not corrode glass at room temperature. Fluoroboric acid is a strong acid, only exists in solution, the common fluoroborate is potassium tetrafluoroborate. Method: Can be prepared by the reaction of Concentrated hydrofluoric acid and boric acid. Uses: used in light metal smelting and electroplating, etc. Even very dilute solution can also be used as fermentation inhibitors, also used for preparing diazonium salts, acetal catalyst, used as an agent for determination of sodium in the presence of magnesium and potassium ions. Aniline as raw materials in concentrated hydrochloric acid reacts with sodium nitrite to generate diazonium salt, then at a low temperature (-10 ℃), diazonium salt reacts with fluoroboric acid, final pyrolysis, can be prepared fluorophenyl. The above information is edited by the chemicalbook of Yan Yanyong.
Toxicity	It has a strong corrosive effect on the skin, mucous membrane, has a irritative effect on the eyes and respiratory system. Even diluted to be very thin, it can hinder fermentation. Maximum allowable concentration is 2.5 mg / m3. If accidentally splashed on the eyes or body, flush eyes with water, wash contaminated body parts thoroughly with soap and water. In severe cases, sent the patient to the hospital. The operator must wear masks, rubber gloves and wear overalls.
Chemical Properties	Transparent colorless liquid. miscible with water or alcohol.
application	Used as acetaldehyde synthesis catalysts, the metal surface cleaning agents, lead electrolytic polishing agents, the diazonium salt stabilizer, etc. Used as Diazonium salts stabilizer, but also for electrolysis industry, etc. Used for cleaning metal surface oxide, silicate film and as a corrosive, for cleaning before aluminum and alloy electroplating. 2.5% solution is for electrolytic polishing of pure aluminum and used as rewashing lotion for removing flux and electroplating parts from the metal substrate, as a catalyst for alkylation and polymerization, preservatives, chemical reagents, as well as the starting materials for preparing various fluoborates. Used to clean metal and alloy surfaces prior to plating. Used for preparing stabilized diazonium salts, manufacturing acetal catalyzed, used as an agent for determination of sodium in the presence of potassium ions and magnesium ions, a catalyst in organic synthesis, but also used for the sponge titanium and its alloys - dissolution and the printed wiring board industry.
Production method	Hydrofluoric acid method is according to the theoretical amount of hydrofluoric acid and boric acid ingredients, slowly adding boric acid to hydrofluoric acid under stirring, the reaction temperature was controlled below 40 ℃, stop mechanical stirring upon heating completed, placed at room temperature for more than 2h, then filtered and purified to obtain fluoroborate finished production. 4HF + H3BO3 → HBF3OH + HF + 2H2O HBF3OH + HF → HBF4 + H2O
