Abstract We report the chemical synthesis of poly( aniline-co - aniline-2,5-disulfonic acid) ) and its composite containing L-hexuronic acid metallic Ag/SiO 2 nanoparticles as a new thermally stable anionic polyelectrolyte for removing safranin dye. The was characterized by IR, UV, cyclic voltammetry, SEM, TEM, TGA, DSC, EDXS elemental analyses. Microscopic images exhibited intensified spherica...

Rubrivivax benzoatilyticus JA2 and other anoxygenic photosynthetic bacteria produce indole derivatives when exposed to aniline, a xenobiotic compound. Though this phenomenon has been reported previously, the role of aniline in the production of indoles is still a biochemical riddle. The present study aims at understanding the specific role of aniline (as precursor or stimulator) in the producti...

Infrared photodissociation spectra of aniline+–M (M = thiophene, furan and phenol) are measured in the 2700–3700 cm–1 region and analyzed by density functional theory calculations. Only a structure with a π-type hydrogen bond is found for aniline+–thiophene. Two structural isomers are identified for aniline+–furan and aniline+–phenol, which have either a π-type or a σ-type hydrogen bond, where ...

Aniline-methanol mixed clusters are ionized by single photon vacuum ultraviolet (VUV, 118 nm) radiation with which absorption to an excited intermediate S(1) state is not required. Aniline ion (An(+)), a series of (An)(n)(+)-(CH(3)OH)(m) (n = 1, 2) cluster ions, and their hydrogenated cluster ions, (An)(n)(+)-(CH(3)OH)(m)H (n = 1, 2) are observed by mass spectrometry. Infrared (IR) absorption s...

The phosphorous-based flame retardant additives poly(m-phenylene methylphosphonate) (PMP) and resorcinol bis(diphenyl phosphate) (RDP) are reacted with bisphenol F aniline–based benzoxazine (BF-a). DSC, rheological analysis, FT-IR, soxhlet extraction reveal the covalent incorporation of both FR additives—initiating phenols in PMP structure as well free generated via transesterification reaction...

Fluorescence yield near-edge spectroscopy (FYNES) above the carbon K edge and temperature programmed reaction spectroscopy (TPRS) have been used as the methods for characterizing the reactivity and structure of adsorbed aniline and aniline derived species on the Ni(100) and Ni(111) surfaces over an extended range of temperatures and hydrogen pressures. The Ni(100) surface shows appreciably high...

The title compound, C(18)H(12)N(6)O(6), was prepared from the reaction of 4-(phenyl-diazen-yl)aniline (aniline yellow) with picryl-sulfonic acid. The dihedral angle formed by the two benzene rings of the diphenyl-diazenyl ring system is 6.55 (13)° and that formed by the rings of the picrate-aniline ring system is 48.76 (12)°. The mol-ecule contains an intra-molecular aniline-nitro N-H⋯O hydroge...
