N-Butyllithium Identification: Chemical Name: n-Butyllithium Synonyms: Butyl-lithiu; NBL, BuLi,1-lithiobutane CAS No.: 109-72-8 Molecular Formula: CH3CH2CH2CH2-Li UN: 2445 Properties: Colorless or slightly yellow, suspended solids and transparent liquid, Soluble in Hexane, cyclohexane or petroleum ether. with n-hexane as solvent, typically made into molar concentration of 1.5 M - 2.5 M range of dilute solution, the density of 0.68 g/ml its quality percentage concentration between 15% - 24%. Specifications: Items Parameter Butyllithium, mol/l ≥ 1.76 2.4 3 Impurity content, w t % ≤ 1 1 1 Chlorobutane, w t % ≤ 0.1 0.1 0.1 Butyllithium ,w t % ≥ Cyclohexane 15 20 25 Hexane 16.5 22.5 28 Application: It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS).It is also broadly employed as a strong base (superbase) in organic synthesis, both industrially and in the laboratory. Packing& Storage: In stainless steel bottle 5-450L or 2000-20000L bulk container; Stored and transported at 20°C down, inflammable and explosive in water or naked fire. Avoid high temperature, impact, do not touch the flame.Do not allow contact with air and water, low temperature preservation.
