Aluminium phenolate is the metalloorganic compound with the formula [Al(OC6H5)3]n. 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] [citation needed]
- Al + 3 HOC6H5 → Al(OC6H5)3 + 1.5 H2
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.[citation needed] [4]
