| Hazard Information | Back Directory | [Potential Exposure]
Dibromobenzene is used as a solvent
for oils and in organic synthesis. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ-
ing resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi-
cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Personal Protective Methods: Wear protective eye protec-
tion, gloves, and clothing to prevent any reasonable proba-
bility of skin or eye contact. Safety equipment suppliers/
manufacturers can provide recommendations on the most
protective glove/clothing material for your operation. All
protective clothing (suits, gloves, footwear, and headgear)
should be clean, available each day, and put on before
work. Contact lenses should not be worn when working
with this chemical. Wear splash-proof chemical goggles
and face shield when working with liquid full facepiece
respiratory protection is worn. Employees should wash
immediately with soap when skin is wet or contaminated.
Provide emergency showers and eyewash. | [Shipping]

Class: 3; Labels: 3-Flammable liquid, Technical Name
Required. UN2514 Bromobenzene, Hazard Class: 3;
Labels: 3-Flammable liquid. | [Incompatibilities]
Extremely flammable. May form
explosive mixture with air. 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, and epoxides. | [Chemical Properties]

Pleasant aromatic odor. | [Chemical Properties]
white or off-white powder | [Waste Disposal]
Use a licensed professional
waste disposal service to dispose of this material. All federal, state, and local environmental regulations must be
observed. Consult with environmental regulatory agencies
for guidance on acceptable disposal practices. Incineration
with flue gas scrubbing. | [Uses]
Solvent for oils; ore flotation; motor fuels; organic synthesis. | [Definition]
ChEBI: 1,4-dibromobenzene is a dibromobenzene. | [Purification Methods]
Steam distil the dibromobenzene , then crystallise it from EtOH or MeOH and dry it in the dark under vacuum. Purify it by zone melting. [Beilstein 5 IV 683.] |
