  A process for producing tert-amylphenols is described, comprising reacting isoamylene with phenols in the presence of an inorganic solid acid catalyst or an acidic ion exchange resin catalyst. This process permits efficient production of tert-amylphenols, i.e., 2,4-di-tert-amylphenol and p-tert-amylphenol. These tert-amylphenols are useful as starting materials for preparation of color formers for color photography, additives for resins, oil-soluble dyes, additives for lubricating oils, etc.

  A phenol is reacted with 2-methyl-1-butene and/or 2-methyl-2-butene (isoamylenes) in the presence of an inorganic solid catalyst (e.g. silica-alumina or activated clay) or an acidic sulfonic-acid type ion exchange resin as catalyst, usually at 30 to 120° C at a pressure of 1 to 10 kg/cm2 for from 1 to 7 h, batchwise; the catalyst is removed, and the unreacted isoamylene removed and the concentrate is distilled and purified to yield a corresponding 2,4-di-tert- or para-tert-amylphenol in high purity and good yield. Optionally a diluting hydrocarbon is used; e.g. obtained by hydrogenating an isoprene-extracted C. fraction in the presence of a metallic (P; Ni) hydrogenation catalyst.
