Fluorobenzene

Description

Fluorobenzene is a colourless, highly flammable liquid, stable and incompatible with oxidising agents. It is not compatible with oxidising agents such as perchlorates, peroxides, permanganates, chlorates, nitrates, chlorine, bromine and fluorine, ammonium nitrate, chromic acid, halogens, and nitric acid. It is used as an insecticide and as a reagent for plastic and resin polymers.

Chemical properties

colourless liquid

Chemical properties

Fluorobenzene is a colorless liquid.

The Uses of Fluorobenzene

Fluorobenzene is used as a reagent for plastic or resin polymers. It acts as a solvent for highly reactive species. On fluorination of fluorobenzene it gives 1,2-difluorobenzene. It is also used as a material in making medicine.

The Uses of Fluorobenzene

Insecticide and larvicide intermediate, identification reagent for plastic or resin polymers.

What are the applications of Application

Fluorobenzene is a fluorinated building block used in various chemical synthesis projects

Definition

ChEBI: The simplest member of the class of monofluorobenzenes that is benzene carrying a single fluoro substituent.

General Description

A clear, colorless liquid with a characteristic aromatic odor. About the same density as water. Flash point 5°F. Vapors heavier than air. May irritate the skin, eyes, and mucous membranes. Used as an insecticide, larvacide and as a reagent for plastic or resin polymers.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

Incompatible with strong oxidizing agents.

Hazard

Flammable, dangerous fire risk. Irritant.

Health Hazard

Irritating to skin, eyes and mucous membranes. Repeated exposure of skin may cause dermatitis due to defatting action. Chronic inhalation of vapors or mist may result to damage to lungs, liver and kidneys. Acute vapor exposures can cause symptoms ranging from coughing to transient anesthesia and central nervous system depression.

Flammability and Explosibility

Highly flammable

Safety Profile

: Mddly toxic by ingestion and inhalation. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, use water spray, mist, foam, dry chemical, CO2. When heated to decomposition it emits toxic fumes of F-

Potential Exposure

Fluorobenzene is used as an insecti cide and as a reagent for plastic or resin polymers.

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 the skin,remove contaminated clothing and wash immediately withsoap and water. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR if heartaction has stopped. Transfer promptly to a medical facility.When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Donot make an unconscious person vomit. Medical observationis recommended for 24-48 h after breathing overexposure,as pulmonary edema may be delayed.

storage

Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Fluorobenzene must be stored to avoid contact with oxidizers since violent reactions occur. Store in tightly closedcontainers in a cool, well-ventilated area. Sources of ignition, such as smoking and open flames, are prohibitedwhere fluorobenzene is handled, used, or stored. Metal containers involving the transfer of=gallons or more of fluorobenzene should be grounded and bonded. Drums must beequipped with self-closing valves, pressure vacuum bungs,and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers offluorobenzene.

Shipping

UN2387 Fluorobenzene, Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Dry fluorobenzene for several days with P2O5, then fractionally distil it. [Beilstein 5 H 198, 5 IV 632.]

Incompatibilities

Vapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, perox ides, permanganates, perchlorates, chlorine, bromine, fluo rine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
