Abstract

Alkylphenols are manufactured by reacting phenols with olefins, stripping the reaction mixture by means of an inert gas, cooling the phenol-containing gas mixture and removing the unconverted phenol. The products are starting materials for the manufacture of dyes, pesticides, pharmaceuticals, emsulfiers, dispersing agents, stabilizers, antioxidants, plasticizers, corrosion inhibitors, disinfectants, seed dressings, stabilizers against ageing, crop protection agents and scents.
