Main Uses:n-Butyllithium has extensive applications in organic synthesis. It can act as a strong base in various organic reactions, such as rearrangement reactions, substitution reactions, condensation reactions, etc. n-Butyllithium can also be used to synthesize organolithium compounds and organometallic compounds, serving as a solvent and reducing agent.
Used to initiate anionic polymerization of conjugated dienes. Through living polymerization pathways, it can synthesize polymers with specified structures such as linear, star, block graft, and telechelic types. It can also be used to prepare low-cis polybutadiene rubber, isoprene rubber, solution styrene-butadiene rubber, thermoplastic rubber, liquid rubber, thermosetting resins, coatings, etc.
