FALLING FILM ALUMINOXANE PROCESS

摘要

FALLING FILM ALUMINOXANE PROCESS Alkylaluminoxanes are made by conducting a solution of an alkylaluminum (e.g., trimethyl aluminum) in an inert solvent to the top of an upright hollow column and allowing the solution to flow as a thin film down the inner surface of the column while passing a wet inert gas (e.g., nitrogen) up through the column such that the wet inert gas contacts the thin falling film of alkyl aluminum solution forming alkylaluminoxane.
