Enzymatic Synthesis of Biobased Polyesters and Polyamides
Nowadays, “green” is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be “green”, being associated with massive energy consumption and severe pollution problems (for example, the “Plastic Soup”) as a public stereotype. To achieve green polymers, three elements sh...
متن کاملBiocatalytic synthesis of fluorinated polyesters.
The biocatalytic synthesis of fluorinated polyesters from activated diesters and fluorinated diols has been investigated. The effects of time, continuous enzyme addition, enzyme concentration, and diol chain length were studied to determine the factors that would limit chain extension, such as enzyme inactivation, enzyme specificity, the equilibrium position for the reaction, hydrolytic side re...
متن کاملSynthesis and Verification of Biobased Terephthalic Acid from Furfural
Exploiting biomass as an alternative to petrochemicals for the production of commodity plastics is vitally important if we are to become a more sustainable society. Here, we report a synthetic route for the production of terephthalic acid (TPA), the monomer of the widely used thermoplastic polymer poly(ethylene terephthalate) (PET), from the biomass-derived starting material furfural. Biobased ...
متن کاملSterically hindered malonamide monomers for the step growth synthesis of polyesters and polyamides.
A new amide monomer for step growth polymerisation is reported: the chemistry exploits a bulky malonamide for the synthesis of polyesters and polyamides. No additives are needed and the only by-product, an amine, can be recycled.
متن کاملTerephthalic acid–4,4′-bipyridine (2/1)
In the title compound, 2C(8)H(6)O(4)·C(10)H(8)N(2), the 4,4'-bipyridine mol-ecule is located on an inversion centre. In the crystal structure, strong inter-molecular O-H⋯N hydrogen bonds between the terephthalic acid and 4,4'-bipyridine mol-ecules lead to the formation of chains with graph-set motif C(2) (2)(8) along the diagonal of the bc plane.
