Yellow pyoctanine Chemical Properties,Uses,Production
Chemical Properties
Auramine is a yellow crystalline powder or flaky material.
Uses
Yellow dye for paper, textiles, leather; antisep- tic; fungicide.
Preparation
(a) will Sulphur dissolved in 4-(4-(Dimethylamino)benzyl)-N,N-dimethylbenzenamine?methane. Add in ammonia and sodium chloride, ammonia in 175 ℃ heat the mixture, with hot water extraction dye and salting out (GP53614); (b) Bis (4 – (dimethylamino) phenyl) methanone and ammonia and Zinc chloride in a total of 150 ~ 160 ℃ heat (GP 29060). Free base is to add the same amount of naoh aqueous solution hydrochloride, sodium carbonate and ammonia and have to.
Definition
ChEBI: A member of the class of imines that is benzophenone imine carrying two dimethylamino substituents at positions 4 and 4'. The hydrochloride salt is the biological stain 'auramine O'
General Description
Yellow crystalline powder or yellow needles.
Reactivity Profile
Yellow pyoctanine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.
Hazard
Confirmed carcinogen.
Health Hazard
Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
Agricultural Uses
Fungicide: Auramine is used industrially as a dye or dye intermediate for coloring textiles, paper, and leather. Also used as an antiseptic (a powerful antiseptic in ear and nose surgery and in gonorrhea treatment)
Trade name
WAXOLINE YELLOW O®
Potential Exposure
Auramine is used industrially as a dye or dye intermediate for coloring textiles; paper, and leather. Also used as an antiseptic (a powerful antiseptic in ear and nose surgery, and treatment of gonorrhea) and fungicide. Human exposure to auramine occurs principally through skin absorption or inhalation of vapors. Low-level dermal exposure to the consumer may occur but would be limited to any migration of auramine from fabric, leather, or paper goods.
Shipping
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste Disposal
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incinerate in furnace with afterburner and scrubber.
