A small set of unsymmetrically substituted acene derivatives containing either aniline or dithiocarbamate moieties was synthesized. A stepwise, one-pot procedure was used to transform appropriate acenequinones to aniline-linked acenes in one step with moderate yields. A heretofore-unreported carbon disulfide activation process involving the formation of a trialkylammonium dithiocarbamate interm...

The effect of three aromatic amines namely aniline (AN), dimethyl aniline (DMAN) and diethyl aniline (DEAN) on emission properties of a coumarin derivative 6-methyl-3azidoacetyl coumarin (6M3AAC) in acetonitrile was studied by means of steady state fluorescence spectroscopy. The quenching of fluorescence intensity was observed in the presence of amines. The quenching process was characterized b...

Singlet Oxygen, Radicals, Fluorescein, Diphenylisobenzofuran, Reversed Micelles The 1,3-diphenylisobenzofuran oxidation reaction was investigated in methanolic and dodecylammonium propionate reversed micellar solutions using fluorescein sodium as photosensitizer. It was found that aniline remarkably enhanced the furan oxidation in methanolic solutions but inhibited it in reversed micellar solut...

The 2,4,6-triphenylthiapyrylium ion has been obtained imprisoned inside the supercages of the tridirectional, large pore zeolites Y and beta via ship-in-a-bottle synthesis from chalcone and acetophenone in the presence of hydrogen sulfide. The resulting solids are efficient and robust photocatalysts that are able to degrade phenol and aniline in water with a higher efficiency than the P-25 TiO(...

The title compound, C(15)H(14)N(2)O·0.67H(2)O, was prepared by the reaction of 4-acetoamine-benzaldehyde and aniline. The asymmetric unit contains six organic mol-ecules and four water mol-ecules. The dihedral angles between the aromatic ring planes in each organic mol-ecule vary from 42.4 (2) to 53.8 (2)°. In the crystal, an extensive network of inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen ...

The basic retention mechanisms of reversed-phase and hydrophilic-interaction liquid chromatography (HILIC) were quantitatively analyzed using simple molecular mechanics (MM) calculations. The model bonded phases were composed of an alkyl chain bonded to siloxane-like molecules. The head of the alkyl chain was a hydroxyl group, used to study retention mechanisms of HILIC. The standard analytes w...

Application of effective remedies of fight against salt sedimentation gives the chance of creation of the reverse, closed and drainless systems conforming to requirements of modern production and ecology. Salt sedimentation inhibitors at an additive to water from 2,0 to 10 g/m3 for 90% and more prevent scaling on a surface of heatexchange devices, boilers, pipelines, etc. For the purpose of dev...

The kinetic study on the oxidation of aniline with oand p-methylaniline by ammonium persulfate (APS) has been carried out. The course of copolymerization was investigated by UV-vis spectroscopic method. Structural characterization was studied by FT-IR spectral analysis. The electronic spectra of the copolymers poly(aniline-co-p-toluidine) and poly(aniline-co-o-toluidine) show hypsochromic shift...

Aniline is a toxic organic pollutant and raw material in industries. In this study, the start-up of sequencing batch reactor for treating aniline wastewater was assessed functional microbial clusters were analyzed after enrichment denitrifying phosphate-accumulating organisms (DNPAOs). The degradation subsequent removal NH4+-N mainly happened aerobic condition, denitrification conducted both an...
