11-Aminoundecanoic acid is an organic compound with the formula H2N(CH2)10CO2H. This white solid is classified as an amine and a fatty acid. 11-Aminoundecanoic acid is a precursor to Nylon-11.[1]
Preparation
As practiced by Arkema, 11-aminoundecanoic acid is prepared industrially from undecylenic acid, which is derived from castor oil.[2] Undecylenic acid undergoes anti-Markovnikov hydrobromination in the presence of benzoylperoxide (BPO):
Conversion of the bromide to the amine completes the synthesis:
