Synthesis of terephthalic acid via Diels-Alder reactions with ethylene and oxidized variants of 5-hydroxymethylfurfural.
Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA. Here, routes to PTA starting from oxidized products of 5-hydroxymethylfurfural (HMF) that can be produced from biomass are reported. These routes involve Diels-Alder ...
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.
متن کامل4,4′-Bipyridine–terephthalic acid (1/1)
The asymmetric unit of the title compound, C(10)H(8)N(2)·C(8)H(6)O(4), consists of one half-mol-ecule of each moiety, 4,4'-bipyridine (bpy) and terephthalic acid (bdc), both being located on crystallographic inversion centers. They are linked together via strong inter-molecular O-H⋯N hydrogen bonds, forming infinite chains propagating along [1-21]. The chains are further connected through C-H⋯O...

15 صفحه اولSelf-Assembled Microwires of Terephthalic Acid and Melamine
Self-assembled microwires of terephthalic acid (TPA) and melamine are prepared through the evaporation of water in a solution mixture of TPA and melamine. The microwires were characterized by using scanning electron microscope (SEM), attenuated total reflection infrared (ATR-IR) spectra, and cross-polarized optical microscopy (CPOM). The TPA•M microwires showed semi-conductive properties.
