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.

Abstract: A process for producing 2,4-di-substituted phenols wherein an olefin is reacted with phenol in the presence of a heterogeneous catalyst comprising an aluminum phenoxide bonded to an acidic solid polymeric resin to preferably form 2,4-di-substituted phenol. A process for preparing a heterogeneous catalyst and a heterogeneous catalyst having the structure(Resin --A--).sub.m Al(--OC.sub.6 R.sub.5).sub.n (11)wherein Resin is a solid polymeric resin having acidic functional groups A, m is 1 or 2, n is 2 or 3 and the R are independently selected from H, alkyl, cycloalkyl, and aralkyl. Preferably, a styrene-divinylbenzene polymeric resin of a macroreticular structure is used for the alkylation process and A is --SO.sub.3 --.

Abstract: A process for the production of a 2,6-dialkylphenol in high yield wherein the alkyl groups are secondary or tertiary with a reduced overall production of 4-alkylphenol by-products by the aluminum phenoxide catalyzed pressure reaction of isobutylene with phenol and a mixture of 2,4-dialkylphenol and 2,4,6-trialkylphenol which may be obtained, in a cyclic process, as a bottom stream from the distillation of the reaction mixture to obtain the 2,6-dialkylphenol product.
