Abstract

Methods for producing biosourced dodecanedioic acid and compositions comprising biosourced dodecanedioic acid are provided. In some embodiments, the method comprises first forming muconic acid biologically from a renewable carbon source, reducing the muconic acid to hexenedioic acid, and then reacting the hexenedioic acid with an unsaturated fatty acid, typically a Delta9 unsaturated fatty acid, in a metathesis reaction to produce dodecenedioic acid. Dodecenedioic acid is then reduced to dodecanedioic acid. Dodecanedioic acid is can be used to form polymers, such as polyamides. Examples of polyamides include nylon, such as nylon 6,12. Nylon 6,12 can be formed by reacting dodecanedioic acid with 1,6-hexamethylene diamine.

Description

[0001] 【Related application】

[0002] This application claims the benefit of US Provisional Application No. 61 / 146,545, filed January 22, 2009, which is hereby incorporated by reference in its entirety. 【Field of Invention】

[0003] The present invention generally relates to the production of dodecanedioic acid from renewable raw materials and its use, for example for the formation of polyamides. [Background of the invention]

[0004] Nylon is the general name for a family of synthetic thermoplastic polyamides used to make things like fabrics, music strings, ropes, screws, and gears. Nylon is also available as a filler, such as glass- and molybdenum sulfide-filled variants.

[0005] Nylon 6 is the most common commercial grade forming nylon. The number suffix indicates the number of carbon atoms contributed by the monomer; first the diamine and then the diacid. For nylon 6,6, typically the diamine is hexamethylenediamine and the diacid is adipic acid. Each of these monome...
