DECAFFEINATION OF LIQUID MEDIUM

A method of decaffeinating liquids such as coffee, which method comprises contacting an effective amount of an adsorbent resin with a liquid solution containing caffeine so as to adsorb caffeine from the liquid solution onto the adsorbent resin, wherein the adsorbent resin is made from a gel copolym...

description A method of decaffeinating liquids such as coffee, which method comprises contacting an effective amount of an adsorbent resin with a liquid solution containing caffeine so as to adsorb caffeine from the liquid solution onto the adsorbent resin, wherein the adsorbent resin is made from a gel copolymer of a monovinyl aromatic monomer and a crosslinking monomer, where the gel copolymer has been post-crosslinked in the swollen state in the presence of a Friedel-Crafts catalyst and can be functionalized with hydrophilic groups if so desired. 36,217-F
