The polymer industry is likely to encounter environmental problems arising from excessive usage of petrochemical sources
and will therefore be required to shift towards bio-based processes. Polyesters represent an exciting area for renewable
feedstocks to be considered due to their wide variety of applications. Interesting carbohydrate-derived monomers for
polyesters include 2,5-furandicarboxylic acid (FDCA) which is a high value derivative from hydroxymethyl furfural (HMF),
itself obtained from the dehydration of C5 and C6 sugars. 1,5-pentanediol (PTO), a potential product from the hydrogenation
of furfural is a hydration product from hemicellulose. Also, succinic acid (SA) can be obtained from fermentation. Despite
the imminent growth of the biomass derived polymers, the process engineering research for these polymerizations is scarce,
which limit their industrial use. Herein this work, we have successfully synthesized poly(1, 5-pentylene succinate) (PTS),
poly(1,5-pentylene 2,5-furandicarboxylate) (PTF) and poly(1,5-pentylene 2,5-furandicarboxylate-co-1,5-pentylene succinate)
(PTFTS) by a two-step process involving polycondensation and azeotropic distillation. 1H NMR confirmed the polyesters’
structure and GPC was used to measure molecular weight. The thermal properties were determined by DSC and TGA. Also,
the kinetic parameters of differential rate equations were estimated. Finally, we performed the simulation in ASPEN Plus™ for
different configurations and solved a multiobjective optimization polyesterification problem by the -constraint method to
obtain the optimum operation conditions and evaluate the performance in terms of sustainability indicators. To the best of our
knowledge, this is the first time a comprehensive work involving synthesis, characterization and process optimization has been
presented for this type of polyesters.
