ABSTRACT:
A process using heterogeneous resin-bonded aluminum phenoxide catalyst to alkylate phenols, the catalyst per se, and a process for making the catalyst. The inventive alkylation process uses ortho-tert-butylphenoxide bonded to a phenolformaldehyde condensation resin heterogeneous catalyst to prepare 2,6-di-tert-butylphenol from isobutylene and ortho-tert-butylphenol.
