The present invention relates to processes for the formation of pyridinedicarboxylic acid (PDCA), in particular, 2,4-pyridinedicarboxylic acid (2,4-PDCA) and 2,5-pyridinedicarboxylic acid (2,5-PDCA), and mono- and diester derivatives thereof, from 3,4-dihydroxybenzoic acid, via a biocatalytic reaction using, for example, a protocatechuate dioxygenase such as protocatechuate 4,5-dioxygenase or protocatechuate 2,3-dioxygenase, and a nitrogen source. The invention also relates to copolymers that comprise the pyridinedicarboxylic acid monomers and derivatives thereof, processes for the formation of the copolymers and uses for the copolymers.
本发明涉及从3,4-二羟基苯甲酸通过生物催化反应,使用原儿茶酸双氧酶例如原儿茶酸4,5-双氧酶或原儿茶酸2,3-双氧酶和氮源等,形成吡啶二甲酸(PDCA),特别是2,4-吡啶二甲酸(2,4-PDCA)和2,5-吡啶二甲酸(2,5-PDCA)及其单酯和双酯衍生物的过程。本发明还涉及包含吡啶二甲酸单体及其衍生物的共聚物,形成共聚物的过程以及共聚物的用途。
