摘要

The efficient removal of primary and secondary amines from organic solutions using a macroporous polymer-supported anhydride is described. The sequestering of primary amines by the anhydride via polymer-bound amide formation is completed within 2–4h at room temperature. Secondary amines require typically 4h for complete sequestration.
