Borane

Borane is a chemical compound with the molecular formula B2H6, also known as diborane. It consists of two boron atoms bonded to six hydrogen atoms, forming a colorless gas at room temperature. With a molecular weight of 27.67 g/mol and CAS number 19287-45-7, borane is an important boron hydride compound used primarily in industrial chemical synthesis and as a reducing agent in various chemical processes.

Borane is a colorless gas at room temperature with a sweet odor. It has a molecular weight of 27.67 g/mol and exists as a dimer (B2H6) under normal conditions. The compound is highly reactive and unstable, decomposing readily in moist air. It is soluble in organic solvents but reacts violently with water. Borane has a low boiling point and is lighter than air, making it easily dispersible in atmospheric conditions.

Borane is primarily used as a reducing agent in organic synthesis and as a catalyst in polymerization reactions. It serves as a precursor for producing other boron compounds and is utilized in the semiconductor industry for doping silicon wafers. Additionally, borane finds applications in rocket fuel formulations due to its high energy content, and in the production of specialized borohydride compounds for various industrial chemical processes.

Borane requires extremely careful handling due to its highly reactive nature and potential health hazards. Personnel must wear appropriate respiratory protection, chemical-resistant gloves, and protective clothing when working with this compound. Work should be conducted in well-ventilated areas or under inert atmosphere conditions. Avoid contact with moisture, heat sources, and incompatible materials. Emergency equipment including eyewash stations and safety showers should be readily accessible during handling operations.

Borane must be stored in tightly sealed containers under inert gas atmosphere to prevent decomposition and unwanted reactions. Storage areas should be cool, dry, and well-ventilated, away from heat sources, moisture, and incompatible materials such as oxidizing agents. Containers should be made of compatible materials and regularly inspected for integrity. Storage facilities must comply with local regulations for handling reactive gases and maintain appropriate fire suppression systems.

Borane exposure requires immediate emergency response due to its reactive nature. In case of skin contact, remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. For eye contact, rinse immediately with water and seek medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. Contact emergency services immediately for any significant exposure incidents.

Borane disposal must be conducted according to local environmental regulations and waste management guidelines. The compound should never be disposed of down drains or into the environment due to its reactive nature. Professional waste disposal services specializing in hazardous chemical waste should handle borane disposal. Small quantities may be neutralized through controlled hydrolysis under professional supervision, but this should only be performed by trained personnel with appropriate safety equipment.

Borane is classified under ADR Class 2 as a compressed gas, requiring specialized transport procedures and packaging. Transportation must comply with international dangerous goods regulations, using approved containers and labeling systems. Vehicles must be properly ventilated and equipped with appropriate safety equipment. Transport should be conducted by trained personnel familiar with hazardous gas handling procedures, and emergency response information must be readily available during transit.

Borane is subject to various chemical safety regulations including REACH registration requirements in Europe. While not currently listed as a Substance of Very High Concern (SVHC), it must comply with CLP classification and labeling regulations. Transportation is regulated under ADR Class 2 dangerous goods provisions. Users must ensure compliance with local workplace safety regulations and environmental protection laws governing the handling and use of reactive chemical compounds.

Borane is available through specialized chemical distributors in Europe, including OYSI, which supplies various chemical compounds to industrial customers across the European market. Due to its reactive nature and regulatory requirements, borane is typically sold only to qualified industrial users with appropriate handling capabilities. Customers should contact authorized distributors directly to discuss specific requirements, quantities, and delivery arrangements for this specialized chemical compound.
