Chemical Properties

p-Chlorobenzotrichloride, an organochloride, is a flammable, water-white liquid.

Uses

Same as o-chlorobenzotrichloride.

Uses

4-Chlorobenzotrichloride is a useful reactant in organic synthesis.

General Description

Clear colorless liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as 4-Chlorobenzotrichloride , are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Health Hazard

ACUTE/CHRONIC HAZARDS: Corrosive; Lachrymator.

Fire Hazard

Flash point data for 4-Chlorobenzotrichloride are not available, however, 4-Chlorobenzotrichloride is probably combustible.

Flammability and Explosibility

Not classified

Safety Profile

Suspected carcinogen. A poison by inhalation. Moderately toxic by ingestion and skin contact. When heated to decomposition it emits toxic vapors of Cl-.

Potential Exposure

Used in agrochemicals manufacture as an intermediate; reaction with HF yields chlorobenzotrifluoride as a major intermediate for several pesticides; for making pharmaceuticals; UV absorbers, and dyestuffs. This chemical is manufactured in high volume (exceeds 1 million pounds per annum) in the United States.

First aid

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 med?ical 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, includ?ing resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalp-Chlorobenzotrichloride 641facility. 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: Storein a secure poison location. Store in tightly closed containers in a refrigerator. Color Code—Red: FlammabilityHazard: Store in a flammable liquid storage area orapproved cabinet away from ignition sources and corrosiveand reactive materials. Prior to working with this chemicalyou should be trained on its proper handling and storage. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045.

Shipping

UN1760 Corrosive liquids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

Incompatibilities

A halogenated aromatic compound. Hydrolyzes to hydrochloric acid and benzoic acid in all forms of moisture. Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from reducing agents, alkaline materials, strong acids, strong bases, amines, nitrides, azo/ diazo compounds, alkali metals, and epoxides.
