For the treatment of 2-naphthol wastewater, homogeneous electro-Fenton process was considered as an effective method but some disadvantages greatly restrict its application. The three-dimensional (3D-EF) system using a nano zero-valent iron-supported biochar (NZVIs-BC) particle electrode and Cu-supported stainless steel (Cu-SSE) proposed to avoid electro-Fenton. In this work, 3D-EF developed, w...

Cyclization of hydrazones derived from 2-acetyl-1-naphthol and 1-acetyl-2-naphthol with triphosgene gave naphtho[1,2-e]-1,3-oxazines, naphtho[2,1-e]-1,3-oxazines or their spiro dimers depending on the molar ratio of triphosgene used for the cyclization.

Background: Naphthalene exposures for most non-occupationally exposed individuals occur primarily indoors at home. Residential indoor sources include pest control products (specifically moth balls), incomplete combustion such as cigarette smoke, woodstoves and cooking, some consumer and building products, and emissions from gasoline sources found in attached garages. The study aim was to assess...

Preparation of 4-aminiquinaldine grafted on silica-coated nano-Fe3O4 particles (Fe3O4@SiO2-AQ) as a novel retrievable heterogeneous nanocatalyst is described. This novel hybrid nanomaterial was applicated for the green synthesis of substituted 2-amino-4H-chromenes via the one-pot condensation reaction of an aldehyde, malononitrile ...

In this paper, the strength and kinetics of two charge-transfer complexes, naphthol-methylviologen and pyrene-methylviologen, are studied using dynamic force spectroscopy. The dissociation rates indicate an enhanced stability of the pyrene-methylviologen complex, which agrees with its higher thermodynamic stability compared to naphthol-methylviologen complex.

In the present paper, we report the synthesis and pharmacological evaluation of a new series of azo compounds with different groups (1-naphthol, 2-naphthol, and N,N-dimethylaniline) and trifluoromethoxy and fluoro substituents in the scaffold. All synthesized compounds (5a-5f) showed the most potent mushroom tyrosinase inhibition (IC₅₀ values in the range of 4.39 ± 0.76-1.71 ± 0.49 µM), compara...

Naphthol is a widely used chemical and medical detection biomarker, but it harmful to human health the environment. Therefore, highly sensitive method for naphthol urgently required. Herein, an electrochemical microsensor simultaneous of isomers was fabricated by in situ growth three-dimensional graphene network (3DGN) on screen-printed electrodes. The exhibited good sensing responses typical (...
