Introduction
Sodium fluoroborate.Quality:2. It is soluble in water and some polar organic solvents, but insoluble in alcohols.3. It is highly corrosive, and acid mineral reactions will occur when encountering acids.Use:1. Sodium fluoroborate is often used as a catalyst and reducing agent in organic synthesis, especially in hydrogenation reactions.2. It is also used as a solvent and electrolyte for platinum metal in the preparation of optical and electronic devices.3. Sodium fluoroborate can also be used as an additive for electroplating, a glass etching agent and a component of erosion solutions.Method:Sodium fluoroborate can be prepared by the reaction of hydrofluoric acid and sodium borate, which produces HBF4 and NaHF2 during the reaction, and then goes through crystallization, drying and other steps to obtain pure products.Safety Information:1. Sodium fluoroborate is irritating and corrosive, and should be avoided in contact with the skin and eyes, and avoid inhaling its dust or vapor.2. Wear appropriate protective gloves, glasses, and a protective face shield when using.4. When storing and transporting sodium fluoroborate, it should be kept away from acids and combustibles, stored in a sealed container, and avoid contact with moisture.
Application
Sodium tetrafluoroborate (NaBF₄, CAS 13755-29-8) is a high-purity inorganic salt valued for its stable, non‑coordinating tetrafluoroborate anion (BF₄⁻). It is widely used as a versatile electrolyte salt in sodium‑ion and lithium‑ion batteries, offering high ionic conductivity, thermal stability, and the ability to form a stable fluorine‑rich interphase, which enhances cycling efficiency and safety. In organic synthesis, NaBF₄ serves as a convenient fluorinating agent and a mild Lewis acid catalyst for constructing bis(indolyl)methanes, 3,4‑dihydropyrimidin‑2(1H)‑ones, and other heterocyclic scaffolds. It also acts as a metal finishing and fluxing agent in aluminium brazing and plating baths, where it improves oxide removal, corrosion resistance, and surface quality. Furthermore, it is a key starting material for preparing ionic liquids and generating boron trifluoride (BF₃) gas, and is used as a glass and ceramics additive to enhance chemical durability.
