Product Name:Methylaluminoxane
English Name:Methylaluminoxane
CAS No.:120144-90-3
Aliases:Methylalumoxane, MAO, Poly(methylaluminoxane)
Molecular Formula:C3H9Al3O3
Physical Properties:Typically supplied as a toluene solution, appearing as a colorless to pale yellow transparent liquid. Sensitive to air and moisture, violently reacts with water. Soluble in aromatic solvents such as toluene. Density approx. 0.9 g/cm³ (20% toluene solution), flash point approx. 4°C. Store sealed in an inert atmosphere at low temperature.
Uses:Mainly used as a cocatalyst in olefin polymerization (e.g., polyethylene, polypropylene), especially in metallocene catalyst systems, where it activates metallocene compounds for efficient catalytic olefin polymerization. Also used as a methylating agent and in the preparation of aluminoxane derivatives in organic synthesis.
Technical Specifications:
Appearance: colorless to pale yellow transparent liquid
Concentration: 10% or 20% toluene solution
Density: approx. 0.9 g/cm³ (20% toluene solution)
