Abstract
Official abstract text for this publication.
An amino-siloxane composition is presented. The amino-siloxane composition includes structure (I): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; R 2 is a C 3 -C 4 aliphatic radical; R 3 is a C 1 -C 5 aliphatic radical or R 4 , wherein R 4 comprises structure (II): and X is an electron donating group. Methods of reducing an amount of carbon dioxide in a process stream using the amino-siloxane composition are also presented.

The invention claimed is: 1. An amino-siloxane composition comprising structure (I): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; R 2 is a C 3 -C 4 aliphatic radical; R 3 is a C 1 -C 5 aliphatic radical or R 4 , wherein R 4 comprises structure (II): and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 2. The amino-siloxane composition according to claim 1 comprising structure (Ia): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; R 2 is a C 3 -C 4 aliphatic radical; and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 3. The amino-siloxane composition according to claim 1 comprising structure (Ib): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 4. The amino-siloxane composition according to claim 1 comprising structure (Ic): wherein X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 5. The amino-siloxane composition according to claim 1 , wherein X comprises a CH 3 O— group; a C 2 H 5 O— group; or a morpholine group. 6. A reaction product of the amino-siloxane composition of claim 1 with carbon dioxide. 7. An adduct of an amino-siloxane having structure (I) and carbon dioxide wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; R 2 is a C 3 -C 4 aliphatic radical; R 3 is a C 1 -C 5 aliphatic radical or R 4 , wherein R 4 comprises structure (II): and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical, wherein the adduct is liquid under ambient conditions. 8. The adduct according to claim 7 , wherein X comprises a CH 3 O— group; a C 2 H 5 O— group; or a morpholine group. 9. The adduct according to claim 7 , wherein the amino-siloxane has structure (Ia): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; R 2 is a C 3 -C 4 aliphatic radical; and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 10. The adduct according to claim 7 , wherein the amino-siloxane has structure (Ib): wherein R 1 is independently at each occurrence a C 1 -C 5 aliphatic radical; and X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical. 11. The adduct according to claim 7 , wherein the amino-siloxane has structure (Ic): wherein X comprises an R 5 O— group; an R 5 S group; or a morpholine group, wherein R 5 is independently at each occurrence a C 1 -C 5 aliphatic radical.
