Industrial N-Butyllithium Polymerization Catalyst CAS 109-72-8

Products Description

What is Industrial n-Butyllithium polymerization catalyst CAS 109-72-8 ?

n-Butyllithium (CAS No.: 109-72-8), also known as butyl lithium or Butyllithium, is an important organic lithium compound with a molecular formula of C4H9Li and a molecular weight of approximately 64.06 g/mol. It typically exists as a solution in saturated hydrocarbon solvents such as hexane and cyclohexane, appearing as a light brown or yellow transparent liquid.
The density of n-Butyllithium solution is approximately 0.68 g/mL (20°C), with a melting point of -95°C, boiling point of 80°C, and extremely low flash point (-22°C to -12°C). It reacts violently or even ignites upon contact with water or oxidants, requiring strict isolation from air and moisture during storage.

Basic Info

Industrial n-Butyllithium polymerization catalyst CAS 109-72-8

Uses

n-Butyllithium reagent reacts with transition metal halides to form butyl-metal complexes (e.g., butyl titanium and butyl zirconium), which serve as catalysts for olefin polymerization. It also participates in reactions analogous to Grignard reagents to generate butylcopper or butylzinc reagents.

Safety Information

Hazards:
Flammable (UN 3399, Class 4.3 dangerous goods).
Corrosive, contact with skin or eyes can cause severe burns.
Reacts violently with water, releasing flammable gas (hydrogen).
Safety measures:
Operation must be carried out in a fume hood, avoid contact with fire, water and oxidants.
Wear protective equipment (gloves, goggles, protective clothing).
