Used to make dyes and printing ink. 2,4,6-Trichloroaniline is a chemical compound with a formula of C6H4Cl3N. Azophenin, C 30 H 24 N 4, is prepared by warming quinone dianil with aniline, by melting together quinone, aniline and aniline hydrochloride, or by the action of aniline on para-nitrosophenol or para-nitrosodiphenylamine. Pubchem - ANILINE HYDROCHLORIDE; Wikipedia - Anilinium chloride. The positive charge is neutralized by the negative charge on the chloride ion. Weinheim: wiley-VHC. Fuchsine is an amine salt and has three amine groups, two primary amines and a secondary amine. DSSTox_GSID_20093. Through one of the side tubes is passed dry gaseous chlorine mixed with dry carbon dioxide (equal volumes). Isorosinduline is obtained from quinone dichlorimide and phenyl-β-naphthylamine; rosinduline from benzene-azo-α-naphthylamine and aniline and naphthinduline from benzene-azo-α-naphthylamine and naphthylamine. MDL number MFCD00012958. The indulines may be subdivided into the following groups: (1) benzindulines, derivatives of phenazine; (2) isorosindulines; and (3) rosindulines, both derived from naphthophenazine; and (4) naphthindulines, derived from naphthazine. Names IUPAC name. MDL number MFCD00012958. They possess a strong metallic lustre and a green yellow color. ", "Note sur les étoffes de soie teintes avec la fuchsine, et réflexions sur le commerce des étoffes de couleur. The crystals pictured at the right are of basic fuchsine, also known as basic violet 14, basic red 9, pararosanaline or CI 42500. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. In solution with phenol (also called carbolic acid) as an accentuator[15] it is called carbol fuchsin and is used for the Ziehl–Neelsen and other similar acid-fast staining of the mycobacteria which cause tuberculosis, leprosy etc. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. Through one of the side tubes is passed dry gaseous chlorine mixed with dry carbon dioxide (equal volumes). Molecular Weight 129.59 . COVID-19 is an emerging, rapidly evolving situation. All structured data from the file and property namespaces is available under the. aniline. aniline dihydrofluoride . *Please select more than one item to compare Basic fuchsine in aqueous solution. This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. The first reaction giving a clue to their constitution was the isolation of the intermediate azophenin by O. Witt, which was proved by Fischer and Hepp to be dianilidoquinone dianil, a similar intermediate compound being found shortly afterwards in the naphthalene series. It is useful as an intermediate in chemical reactions. aniline hydrochloride. Phenylhydrazine was the first hydrazine derivative characterized, reported by Hermann Emil Fischer in 1875. Benzinduline (aposafranine), C18H13N3, is a strong base, but cannot be diazotized, unless it be dissolved in concentrated mineral acids. Chemistry, Properties, Applications. "Use of rosaniline hydrochloride dye for atmospheric SO, "Action of Bichloride of Carbon on Aniline", "Comptes rendus hebdomadaires des séances de l'Académie des sciences. Their structure differs from the structure shown above by the absence of the methyl group on the upper ring, otherwise they are quite similar. 4-Methoxy-1-aminobenzene hydrochloride. This page was last edited on 13 August 2020, at 07:43. [2], Dry aniline are dissolved in dry carbon tetrachloride, and placed in a flask fitted with a mechanical stirrer. [6][7] He prepared it by reduction of a phenyl diazonium salt using sulfite salts. As well as dying textiles, fuchsine is used to stain bacteria and sometimes as a disinfectant. The actual composition of basic fuchsine tends to somewhat vary by vendor and batch, making the batches differently suitable for different purposes. From Wikimedia Commons, the free media repository. When warmed with aniline it yields anilido-aposafranine, which may also be obtained by the direct oxidation of ortho-aminodiphenylamine. The positive charge can be thought of as residing on the central carbon atom and all three "wings" becoming identical aromatic rings terminated by a primary amine group. [3], Occupational exposure to 2,4,6-trichloroaniline may occur through inhalation and dermal contact with this compound at workplaces where 2,4,6-trichloroaniline is produced or used (SRC).
