Aluminum isopropoxide, also known as isopropyl aluminum oxide, abbreviated as AIP, is an oxide of aluminum. It is a useful reagent in organic synthesis. Aluminum isopropoxide on the market is mostly white translucent block, cylindrical small block solid or powder, soluble in isopropanol, ethanol, toluene, benzene, carbon tetrachloride, chloroform and other organic solvents (easy to dissolve when heated to 70 °C), decomposed when it meets water, has strong water absorption, and is easily decomposed into aluminum hydroxide and isopropanol.)Aluminium isopropoxide is usually described with the formula Al(O-i-Pr)3, where i-Pr is the isopropyl group (CH(CH3)2). This colourless solid is a useful reagent in organic synthesis. It is used in MPV reductions of ketones and aldehydes and the Oppenauer oxidation of secondary alcohols. Aluminum isopropoxide is synthesized by the reaction of isopropanol and aluminum under the catalysis of alumina. Raw material consumption quota: isopropyl alcohol 1255kg/t, aluminum 166kg/t.

Fire Hazard

The flash point of this compound is 26°C (79°F) (Bretzinger and Josten). It is less flammable than the sec- and tert-alkoxides of alkali metals. Ignition may occur when this compound is heated in moist air.It decomposes in water. The reaction is exothermic, producing isopropanol. It may decompose when heated to 250°C (482°F), producing highly flammable isopropyl ether.

Solutions of aluminum alkoxides obtained by interaction of aluminum metal with methyl, ethyl, and isopropyl alcohols were studied by 27Al and 13C NMR and small-angle X-ray scattering. The structure of polynuclear complexes was refined by comparison of their calculated dimensions with small-angle X-ray scattering data.

RSC Adv., 2022, 12, 33970-33980

In this study, we investigate H-transfer reduction reactions of carbonyl compounds (aldehydes and ketones) catalysed by aluminium isopropoxide immobilised over mesoporous solid supports. The use of high surface area supports for the immobilisation is expected to enhance the dispersion of the aluminium isopropoxide catalyst.
