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.

Thermally stable, 3D rod-like, nanosized, pH-stable Fe–Al metal–organic-framework with terephthalic acid as a linker surface area 120.255 m 2 g −1 was synthesized solvothermally for fluoride adsorption and the photodegradation of rhodamine B/methylene blue (pH 2–11).

The separation of the binary mixture water-acetic acid by direct distillation is not suitable for industrial applications because of the presence of a tangent pinch on the pure water end. The problem is overcome via heterogeneous azeotropic distillation adding a third component, the entrainer, generally immiscible with water. With particular reference to terephthalic acid production process, we...

The title 2:1 co-crystal, 2C12H10N2·C8H6O4, crystallizes with one mol-ecule of 4-[(E)-2-(pyridin-2-yl)ethen-yl]pyridine (A) and one half-mol-ecule of terephthalic acid (B) in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOH⋯Npyridine synthons, forming linear aggregates of composition -A-B-A-B-. Further linkage through weak C-H⋯O and C-H⋯π inter-actions g...

The reactions of N1,N2-Di-boc-1,2,4-triaminobutane with bridged dicarboxylic acids afford the corresponding bis-amides from which – after removal of the Boc groups – bis(N,N′-bidendate) ligands H2NCH2CH(NH2)(CH2)2NHCO-X-CONH(CH2)2CH(NH2)CH2NH2 can be obtained. New examples are the reactions of the triaminobutane with pyridine-2,6-dicarboxylic acid, with phenylene-1,4-diacetic acid, with terepht...

The asymmetric unit of the title solvate, C(20)H(14)O(4)·2C(2)D(6)OS, contains half of the substituted terephthalic acid mol-ecule and one solvent mol-ecule. The centroid of the central benzene ring in the acid mol-ecule is coincident with a crystallographic inversion center. Neither the carboxyl nor the phenyl substituents are coplanar with the central aromatic ring, showing dihedral angles of...
