DIETHYLALUMINUM ETHOXIDE Chemical Properties,Usage,Production

Chemical Properties

colorless liquid

Uses

Diethylaluminum ethoxide is a base in aldol condensation reactions; it can be used as a reducing agent in the preparation of Ni catalysts.

Flammability and Explosibility

Spontaneously flammable in air (pyrophoric)

storage

The reagent itself is pyrophoric and its solutions are highly flammable  and air and moisture sensitive and should be handled under an inert atmosphere. Use in a fume hood.
