Aminoenanthic acid

The amino acid and the ammonium chloride may conveniently be separated by passing through a column of ion-exchange resins. The amino acid melts at 195°C.

The co-aminoenanthic acid is polymerised in an aqueous solution under nitrogen at 14-15 atm pressure at 250-260°C. The process takes several hours. ...

Nylon 9 or poly(o)-pelargonamide) is produced in Russia together with nylon 7, poly (aminoenanthic acid) as described above. In the U.S., Kohlhase et al. [67] developed a route to nylon 9 via ozonolysis of unsaturated fatty acids like those that can be obtained from soybean oil. The glycerol fatty acid esters of oleic, linoleic, and linolenic acids are transesterified with methanol to form methyl esters. The esters are then cleaved via ozonolysis to yield methylazelaldehyde and byproducts that are removed. The purified product is reacted with ammoiua and then reduced over Raney nickel to yield a methyl ester of the amino acid ...
