The oxidation of aniline to azobenzene was conducted in the presence of either monolayer graphene (EG) or graphene-oxide-like surface, such as GOx, under ultra-high vacuum conditions maintaining a 365-nm UV light exposure to enhance the oxidation reaction. The surface-bound products were investigated using micro Raman spectroscopy, high-resolution photoemission spectroscopy, and work function m...

Increasing numbers of workers in industry are working a novel or unusual 12-hr workshift in which the exposure time is longer and the recovery period is shorter than for a standard 8-hr workshift. Experiments were conducted to examine the effects of altering the exposure schedule of rats from 8 hr/day for 5 days to 12 hr/day for 4 days on the toxicity resulting from the inhalation of aniline at...

Background and purpose: Aniline is widely used as raw material in many chemical industries. The aim of this study was to survey the photocatalytic degradation of aniline using magnesium oxide nanoparticles from aqueous solutions. Materials and methods: An experimental study was carried out in a 2 L volume batch reactor. Various parameters such as pH (3-11), dose of nanoparticles (0.1-1), con...

This study was carried out in two stages. In the first stage; 2-oxo-2-phenylethyl-2-aminobenzoate (OPA) compound, which an aniline derivative, synthesized by starting appropriate components. Then, poly(OPA) obtained via chemical polymerization of OPA presence ammonium peroxydisulfate (APS) as initiator and DMF solvent. Poly(OPA)/Bentonite (BNT) nanocomposite effectively dispersing inorganic nan...

Six nonlinear, optical chromophores, Z1–Z6, based on the bis(N,N-diethyl)aniline-derived donor and thiolated isophorone bridge, were designed synthesized. The was applied in a chromophore with as an electron bridge for first time. In particular, parts of chromophores Z2–Z6 modified different functional groups, including tert-butyltrimethylsilane tert-butyl(methyl)diphenylsilane derivative: 1,3-...

Comprehensive studies of the molecular and electronic structures, vibrational frequencies, and infrared and Raman intensities of the aniline radical cation, C6H5NH2 1 have been performed by using the unrestricted density functional ~UB3LYP! and second-order Møller–Plesset ~UMP2! methods with the extended 6-31111G~df,pd! basis set. For comparison, analogous calculations were carried out for the ...

The chemotherapeutic agent known as 5-fluorouracil (5-FU) is an artificial fluoropyrimidine antimetabolite that has been widely used for its antineoplastic properties. Cocrystals of with five different Schiff bases (benzylidene-urea (BU), benzylidene-aniline (BA), salicylidene-aniline (SA), salicylidene-phenylhydrazine (SPH), and para-hydroxy benzylideneaniline (HBA)) are reported in this study...
