OXIDATIVELY STABLE ORGANOSILICATES FOR CO2 CAPTURE
This abstract first appeared for US patent application 18915714 titled 'OXIDATIVELY STABLE ORGANOSILICATES FOR CO2 CAPTURE
Original Abstract Submitted
Amine-functionalized organosilica materials are provided that have improved stability when exposed to oxidizing/oxygen-containing environments during cycling of temperature, such as the cycling of temperature that occurs when using a material as a sorbent during successive adsorption/desorption cycles. Methods of performing COsorption/desorption with improved stability of the organosilica sorbent material are also provided. The improved stability is achieved in part by using amine-functionalized organosilica materials where the amine-functionalization is provided by functional groups that include primary amines but do not include secondary amines. Still further improvements in stability can be achieved when the functionalization is provided by a functional group that includes a primary amine while also not having any hydrogens on a carbon atom that is in the beta position relative to the primary amine.
