Epoxidation of porous amine-based phenylic polymer resins and methods of use for carbon dioxide capture

Abstract

A solid epoxidized aminated porous phenylic polymer without the use of a porous silica support structure is described herein along with its method of synthesis and its application to the adsorption of carbon dioxide (CO2) from a feed gas. An illustrative example of the use of 1,2-propylene oxide (epoxypropane) to epoxidize a solid porous phenylic aminated resin substrate based upon a simple one-step reaction at room temperature is described herein. This epoxidized IER exhibits approximately a three-fold improvement in lifetime upon exposure to oxygen in dry air at 110° C.-120° C. as compared to the non-epoxidized polymeric starting material.
