Aluminium phenolate is the metalloorganic compound with the formula [Al(OC6H5)3n. It is a white solid. 27Al NMR studies suggest that aluminium phenolate exists in benzene solution as a mixture of dimer and trimer. [2] The compound is can be prepared by the reaction of elemental aluminium with phenol: [3]
The compound is used as a catalyst for the alkylation of phenols with various alkenes. For example, the ethylphenols are generated commercially by treating phenol with ethylene in the presence of a catalytic amount of aluminium phenolate. [4]
The aluminum phenoxide catalyst was prepared by adding 4.5 g. (1⁄6 formula wt.) of aluminum turnings in small amounts and with vigorous stirring to 300 g. of phenol at 165° under a nitrogen atmosphere.
2‑Ethylphenol and 2,6‑diethylphenol are produced industrially by ortho-alkylation of phenol with ethylene in high pressure autoclaves at 320‑340 °C and 20 MPa in the presence of 1‑2% aluminum phenolate.
