摘要

Abstract 12-Aminododecanoic acid and 11-aminoundecanoic acid, monomer precursors for nylon-12 and nylon-11, respectively, have been synthesized from vernolic (cis-12, 13-epoxy- cis-9-octadecenoic) acid via a reaction sequence that includes the formation of 12- oxododecanoic acid oxime. Saponification of vernonia oil, followed by a low-temperature recrystallization at− 20° C, gave 51% vernolic acid (97% purity, mp 23–25° C). ...
