The Uses of Yellow pyoctanine

Yellow dye for paper, textiles, leather; antisep- tic; fungicide.

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'

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.

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.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

storage

Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with auramineyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from oxidizers. Sources of ignition, such as smoking and open flames, are prohibited where this chemical isused, handled, or stored in a manner that could create apotential fire or explosion hazard. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.
