Potassium boranuide

Potassium boranuide is an inorganic chemical compound with the molecular formula BH4K and CAS number 13762-51-1. This borohydride salt consists of potassium cations and tetrahedral borohydride anions, making it a member of the alkali metal borohydrides family. With a molecular weight of 53.94 g/mol, it serves as an important reducing agent in various chemical applications and synthetic processes.

Potassium boranuide is typically a white crystalline solid at room temperature with high hygroscopic properties, readily absorbing moisture from air. It demonstrates excellent solubility in polar solvents, particularly water and alcohols, forming clear solutions. The compound is generally odorless but may decompose upon exposure to moisture or acids, releasing hydrogen gas. Its ionic structure contributes to its stability under dry conditions.

Potassium boranuide serves primarily as a selective reducing agent in organic synthesis, particularly for converting aldehydes, ketones, and other carbonyl compounds to alcohols. It finds applications in pharmaceutical manufacturing, fine chemical synthesis, and research laboratories. The compound is also utilized in metal processing for reducing metal salts and in specialized analytical procedures where mild reducing conditions are required.

Potassium boranuide requires careful handling using appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of any dust or decomposition products. Avoid contact with acids, oxidizing agents, and moisture during handling. Use non-sparking tools and ensure proper grounding to prevent static discharge.

Potassium boranuide must be stored in tightly sealed containers in a cool, dry environment away from moisture, heat sources, and incompatible materials. Keep containers in a well-ventilated area, separated from acids, oxidizing agents, and halogenated compounds. Storage areas should be equipped with appropriate fire suppression systems and maintained at stable temperatures to prevent decomposition and ensure product stability.

Skin contact with potassium boranuide requires immediate removal of contaminated clothing and thorough washing of affected areas with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care.

Potassium boranuide disposal must comply with local and national hazardous waste regulations as it is classified as dangerous goods. The compound should be collected in appropriate containers and disposed of through licensed chemical waste management companies. Never dispose of it in regular waste streams or pour it down drains. Consider neutralization procedures under controlled conditions before final disposal when permitted by regulations.

Potassium boranuide is classified under ADR Class 4.3 (substances which, in contact with water, emit flammable gases), Packing Group I, indicating high danger level. Transportation requires UN-approved packaging, proper labeling with Class 4.3 hazard labels, and appropriate shipping documentation. Only authorized carriers trained in dangerous goods transport should handle shipments, following strict ADR regulations for safe transport across European roads.

Potassium boranuide is regulated under European REACH legislation requiring registration for commercial use, though it is not classified as a Substance of Very High Concern (SVHC). The compound must comply with CLP regulation for classification, labeling, and packaging. As a dangerous good under ADR Class 4.3, it requires specific transport documentation and handling procedures. Users must follow applicable workplace safety regulations.
