ABSTRACT:
Aluminum is removed from sec-alkyl phenolic compositions containing aluminum in the form of a phenate by first adding aqueous alkali metal hydroxide in stoichiometric excess over said aluminum and then acidifying the mixture with a mineral acid and removing the acidic aqueous phase to leave a substantially aluminum-free sec-alkyl phenolic composition. The method is especially adapted to remove aluminum from the distillation bottoms remaining after distilling product from a sec-alkylation mixture formed by alkylating a phenol with a sec-alkyl precursor olefin using an aluminum phenate catalyst.
