Abstract
Nylon 7 may be produced from biomass derived 6-carbon hydroxymethyl furan compounds as the raw material. The hydroxymethyl furan compounds may be homologated to form an aldehyde that may be aminated to produce an amino carbonyl compound. Hydrogenation/hydro-deoxygenation of the amino-carbonyl compound provides nylon 7.
