AlOEt3

Aluminum triethoxide, with the chemical formula Al(OEt)3, is a metal alkoxide derived from aluminum and ethoxide ligands. It is used primarily as a precursor to aluminum oxide materials and as a Lewis acid catalyst or reagent in some organic and materials chemistry applications. In solution and in solid form, it tends to form oligomeric or polymeric species rather than discrete monomers.

Chemical properties and behavior: Aluminum triethoxide is highly reactive with water and oxygen. Upon exposure to moisture, it hydrolyzes to yield aluminum hydroxide or aluminum oxide species and ethanol. In hydrolysis and thermal treatment, it can dehydrate and condense to form Al2O3, which is the common precursor route to alumina ceramics and coatings. The compound is typically sensitive to air and moisture and is handled under inert or dry conditions. In organic solvents, it can be dispersed or dissolved in certain polar solvents, depending on the degree of aggregation.

Preparation and availability: Al(OEt)3 is produced and sold as a reactive intermediate for sol-gel processes and as a starting material for aluminum-containing resins and coatings. It is often supplied as a solid or as a solution in suitable organic solvents. Its exact formulation can vary by supplier and intended application.

Applications: The primary use of aluminum triethoxide is as a precursor for alumina via hydrolysis or sol-gel routes, enabling the synthesis of porous ceramics, coatings, and thin films. It also serves as a Lewis acid in select organic transformations and can be employed in the preparation of aluminum-containing inorganic-organic hybrids and catalysts.

Safety and handling: Al(OEt)3 is moisture sensitive and reacts with water to release ethanol. It should be stored under dry, inert conditions away from moisture and incompatible materials. Proper personal protective equipment and ventilation are advised when handling.
