METHODS AND COMPOUNDS FOR PRODUCING NYLON 6,6

摘要

Alternating co-polymers of cyclic dicarboxylic acids and cyclic diamines may be used to produce nylon 6,6. Di-substituted furan compounds may be used as the raw material for producing furan-dicarboxylic acids and/or furan-diamines. The furan-dicarboxylic acids and furan-diamines may be copolymerized to produce polymer precursors for nylon 6,6. The polymer precursors may be hydrogenated and/or deoxygenated to produce nylon 6,6.

1. A method for producing nylon 6,6, the method comprising:
converting methylfurfural of formulawherein
X1 is —OH or -halogen,to a furan-dicarbonyl compound of formulawherein
M1 isorand
R is H, or alkyl; converting methylfurfural of formulawherein
X2 is —OH or -halogen,to a furan-diamine of formulawherein
M2 isor copolymerizing the furan-dicarbonyl compound and the furan-diamine to form an alternating copolymer having the structurewherein
n is 2 or more; and converting the copolymer to nylon 6,6.
