  • Catalysts
  • N-Methylation of aniline with methanol at elevated temperatures over acid catalysts gives N-methylaniline and dimethylaniline: C6H5NH2 + 2 CH3OH → C6H5N(CH3)2 + 2H2O N-Methylaniline and dimethylaniline are colorless liquids with boiling points of 193-195 °C and 192 °C, respectively. (wikipedia.org)
  • transition
  • As a part of our systematic studies of the above homologous series regarding the synthesis, characterization and phase transition studies, here the authors report the polarizabilities and orientational order parameter, S in N-(p-n-ethoxybenzylidene)-p-n-alkoxy anilines, 2O.Om with m = 3 to 10 liquid crystalline compounds except with m = 5 which has been already published. (scirp.org)
  • derivatives
  • The N3-substituted derivatives were heated with a mixture of 3-ethyl-4-methylaniline and its hydrochloride to effect displacement of the 6-amino group and simultaneous demethylation of the 2-methoxy group to yield target compounds in good yields. (umassmed.edu)
  • exhibit
  • The rest of the compounds exhibit the nematic LC phase except with m = 10 which shows the smectic-C phase along the nematic phase which is originally not detected by Godzwon et al. (scirp.org)
  • toxic
  • Aniline is acutely toxic, and prolonged exposure can result in hemolytic anemia and tumor formation in the spleen. (environmental-expert.com)
  • In the intestines, Red 2G can be converted to the toxic compound aniline, so there are concerns Red 2G may ultimately interfere with blood haemoglobin, as well as cause cancer. (wikipedia.org)
  • reaction
  • For example, reaction of aniline with sulfuric acid at 180 °C produces sulfanilic acid, H2NC6H4SO3H. (wikipedia.org)
  • The largest scale industrial reaction of aniline involves its alkylation with formaldehyde. (wikipedia.org)
  • This compound is converted to 7 via a ring-closing reaction and decarboxylation. (wikipedia.org)
  • Commercially available, this compound may be used as a building block, e.g. in the preparation of p-bromobiphenyl via the Gomberg-Bachmann reaction. (wikipedia.org)
  • Horseradish peroxidase has an accessible active site, and many compounds can reach the site of the reaction. (wikipedia.org)
  • benzene
  • Traditionally, the weak basicity of aniline is attributed to a combination of inductive effect from the more electronegative sp2 carbon and resonance effects, as the lone pair on the nitrogen is partially delocalized into the pi system of the benzene ring. (wikipedia.org)
  • The NH2 group attached to the benzene ring means that there is a lone pair of electrons that can enter into conjugation with the benzene ring resulting in delocalization in the aniline. (wikipedia.org)
  • acid
  • Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black. (wikipedia.org)
  • Trees and woody plants are killed by a complex group of factors that include parasites, such as fungus and beetles, pollution, such as acid rain and organic compounds, and drought. (wikipedia.org)
  • Oxidation
  • The oxidation of aniline has been heavily investigated, and can result in reactions localized at nitrogen or more commonly results in the formation of new C-N bonds. (wikipedia.org)
  • experimental
  • Optimized experimental and analytical methods were successfully developed following standardized EPA sampling and analysis methods as guidelines for determination of organic compounds dissolved in a suitable solvent able to completely solvate aniline as well as DeconGel components.

  • industrial
  • This approach not only provides more insight into the origin of life but also offers a pathway to acquire enantiopure compounds for industrial applications. (nih.gov)
  • variety
  • Certain intermediates, e.g. the 3-(iodoalkyl) compounds, were converted to a variety of (3-substituted-alkyl)-EMAUs by displacement. (umassmed.edu)
  • studies
  • The existence of metal-nitrogen bond for all pyridine and aniline complexes, except H 2 CdI 4 ·4 An ( An =aniline), is adduced from infrared and far infrared spectral studies. (springer.com)
  • Nitta, Y. "Studies on analgesics of aniline series. (wikipedia.org)
  • Several
  • Several compounds protected mice from lethal intraperitoneal (ip) infections with S. aureus (Smith) when given by the ip route. (umassmed.edu)
  • analysis
  • Decontamination efficacies of DeconGel 1101 were 100% for aniline on all surfaces evaluated including concrete, stainless steel and aluminum as determined by residual swipe analysis. (environmental-expert.com)
  • structure
  • The stability of the new organoiron compound was accorded to the aromatic character of the negatively charged cyclopentadienyls, but they were not the ones to recognize the η5 (pentahapto) sandwich structure. (wikipedia.org)
