  • Patent number: 10875962
    Abstract: A method of making a polyamide copolymer includes subjecting a reaction mixture to conditions sufficient to form the polyamide copolymer, the reaction mixture including adduct A and adduct B. Adduct A is a 1:1 adduct of a diamine having the structure H2N-R1-NH2, or a salt thereof and an aliphatic diacid having the structure HO—C(O)—R2-C(O)—OH, or a salt thereof. Adduct B is a 1:1 adduct of the diamine having the structure H2N-R1-NH2, or a salt thereof, and an aromatic diacid having the structure HO—C(O)—R3-C(O)—OH, or a salt thereof. At each occurrence, R1 and R2 can be independently a substituted or unsubstituted (C1-C20)alkylene. At each occurrence, R3 can be independently a substituted or unsubstituted (C6-C20)arylene. The molar ratio of adduct A to adduct B in the reaction mixture can be about 61:39 to about 90:10.

  • Patent number: 10801046
    Abstract: This document describes biochemical pathways for producing a difunctional product having an odd number of carbon atoms in vitro or in a recombinant host, or salts or derivatives thereof, by forming two terminal functional groups selected from carboxyl, amine, formyl, and hydroxyl groups in an aliphatic carbon chain backbone having an odd number of carbon atoms synthesized from (i) acetyl-CoA and propanedioyl-CoA via one or more cycles of methyl ester shielded carbon chain elongation or (ii) propanedioyl-[acp] via one or more cycles of methyl ester shielded carbon chain elongation. The biochemical pathways and metabolic engineering and cultivation strategies described herein rely on enzymes or homologs accepting methyl ester shielded aliphatic carbon chain backbones and maintaining the methyl ester shield for at least one further enzymatic step following one or more cycles of methyl ester shielded carbon chain elongation.

  • Patent number: 10759741
    Abstract: A solvent is at least partially separated from a catalyst. The catalyst comprises nickel and a bidentate phosphorus-containing ligand. The method for separation involves distilling a catalyst solution. The ratio of 2-pentenenitrile to 3-pentenenitrile in distillation column bottoms is controlled to reduce the amount of 3-pentenenitrile which is isomerized to form 2-methyl-3-butenenitrile. Isomerization of 3-pentenenitrile to 2-methyl-3-butenenitrile and subsequent isomerization of 2-methyl-3-butenenitrile to 2-methyl-2-butenenitrile, and/or hydrocyanation of 2-methyl-3-butenenitrile to methylglutaronitrile represents a loss in adiponitrile yield in a process for making adiponitrile.
