Reddish brown or black liquid.

N,N-DIETHYL-P-PHENYLENEDIAMINE(93-05-0) 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. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Insoluble in water.

This chemical is probably combustible.

DPD is a clear liquid. Molecularweight=164-28; Boiling point=260-262℃; Flash point$110℃.

dark brown to black solid or liquid, depending upon room temperature

Dye intermediate, source of diazonium compounds in diazo copying process.

Used as a dye intermediate and incolor photography. Some p-phenylenediamine compoundshave been used as rubber components, and DFG warns ofdanger of skin sensitization.

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.

Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with DPD youshould be trained on its proper handling and storage. Store in tightly closed containers in a cool, well-ventilated area.Metal containers involving the transfer of this chemicalshould be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers toprocess containers. Drums must be equipped with self-closingvalves, pressure vacuum bungs, and flame arresters. Use onlynonsparking tools and equipment, especially when openingand closing containers of this chemical. Sources of ignition,such as smoking and open flames, are prohibited where thischemical is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard. Wherever thischemical is used, handled, manufactured, or stored, useexplosion-proof electrical equipment and fittings.

Phenylenediamines require a shipping label of“POISONOUS/TOXIC MATERIALS.” They fall in DOTHazard Class 6.1 and Packing Group III.

Contact with strong oxidizers may causefire and explosion hazard.
