Procedure

Aluminum tri(2-n-butoxyethoxide) was prepared by incremental addition of pure aluminum turnings to anhydrous 2-n-butoxyethanol. Accordingly, to a 3-liter flask fitted with condenser, stirrer and inlet for dry N2 2-n-butoxyethanol (944 g, 8.0 moles) was added and heated to a reflux temperature of approximately 160° C. Approximately 5 grams of aluminum turnings were added. Evolution of H2 gas is observed after 2 to 10 hours signifying the reaction has begun. A catalytically effective quantity of HAl(OCH2CH2OBu)4 (prepared in Example 1) added to the reaction flask substantially shortens the induction period required.
