Abstract
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.
