Lithium hexane

Lithium hexane is an organolithium compound with the molecular formula C6H13Li and CAS number 21369-64-2. This chemical substance has a molecular weight of 92.1 g/mol and belongs to the class of alkyllithium reagents. It is classified as extremely hazardous due to its pyrophoric nature, violent reaction with water, and severe skin corrosive properties. The substance carries the danger signal word and requires strict handling protocols in industrial applications.

Lithium hexane is a highly reactive organometallic compound that exhibits pyrophoric properties, meaning it can spontaneously ignite in air. The substance reacts violently with water and moisture, making it extremely water-sensitive. Due to its organolithium nature, it typically appears as a solution in hydrocarbon solvents and must be handled under inert atmosphere conditions. Its corrosive properties make it capable of causing severe skin and eye damage upon contact.

Lithium hexane is primarily used as a strong organometallic reagent in organic synthesis and pharmaceutical manufacturing. It serves as a nucleophilic agent in carbon-carbon bond formation reactions and as a metallating agent for aromatic compounds. The compound is valuable in the production of fine chemicals, pharmaceutical intermediates, and specialty polymers. Due to its high reactivity, it is mainly employed in controlled industrial processes requiring precise handling and inert atmosphere conditions.

Lithium hexane requires extreme safety precautions due to its pyrophoric and corrosive nature. Personnel must wear full protective equipment including chemical-resistant gloves, safety goggles, face shields, and protective clothing. All handling must occur under inert atmosphere (nitrogen or argon) to prevent ignition. Work areas should be equipped with appropriate fire suppression systems and emergency shower facilities. Only trained personnel should handle this substance in well-ventilated areas away from water and ignition sources.

Lithium hexane must be stored under inert atmosphere in tightly sealed containers to prevent contact with air and moisture. Storage areas should be cool, dry, and equipped with fire suppression systems suitable for metal fires. The substance must be kept away from water, oxidizing agents, and incompatible materials. Storage facilities should meet Class 4.2 dangerous goods requirements with appropriate ventilation and temperature control. Regular monitoring of container integrity is essential to prevent leakage and potential fires.

Lithium hexane contact requires immediate emergency response due to its severe corrosive properties. For skin contact, immediately remove contaminated clothing and flush affected areas with copious amounts of water for at least 15 minutes. For eye contact, rinse immediately with water and seek urgent medical attention. If ingested, do not induce vomiting and seek immediate medical care. In case of fire, use Class D fire extinguisher suitable for metal fires, never use water.

Lithium hexane disposal must comply with hazardous waste regulations as it is classified under ADR Class 4.2, Group I. The substance requires specialized disposal through licensed hazardous waste contractors experienced in handling pyrophoric materials. Small quantities can be carefully neutralized by trained personnel using appropriate quenching agents under controlled conditions. All disposal activities must follow local environmental regulations and waste classification codes. Documentation of proper disposal chain is mandatory for regulatory compliance.

Lithium hexane is classified under ADR Class 4.2 (Substances liable to spontaneous combustion), Packaging Group I, indicating maximum transport restrictions. Transportation requires specialized containers meeting UN packaging standards and proper hazard labeling with GHS02 and GHS05 pictograms. Shipments must be accompanied by appropriate transport documentation and emergency response information. Only certified carriers experienced in dangerous goods transport should handle this substance, with strict compliance to ADR regulations throughout the transport chain.

Lithium hexane is subject to comprehensive chemical safety regulations including REACH registration requirements in Europe and CLP classification obligations. The substance carries mandatory hazard classifications as Pyrophoric Solid Category 1, Water-reactive Category 1, and Skin Corrosive Category 1A. While not listed as an SVHC (Substance of Very High Concern), it requires safety data sheets, proper labeling, and workplace exposure controls. Users must comply with occupational safety regulations and environmental protection measures.
