3-Chlorobenzotrifluoride Chemical Properties,Usage,Production

Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

Intermediate in manufacturing of dyes and pharmaceuticals, dielectrics, insecticides.

Uses

3-Chlorobenzotrifluoride is used as an intermediate in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.

General Description

A water-white liquid with an odor like moth balls. Flash point between 65-108°F. Insoluble in water and denser than water. Toxic by inhalation. Liquid contact may irritate skin and eyes.

Air & Water Reactions

Highly flammable. On contact with water 3-Chlorobenzotrifluoride can evolve hydrogen fluoride, a highly toxic and corrosive gas. [AAR, 1999]. Insoluble in water and denser than water.

Reactivity Profile

Simple aromatic halogenated organic compounds are very unreactive; halogenated aliphatic compounds are moderately or very reactive. For both subgroups, reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Hazard

Moderate fire risk.

Health Hazard

May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Purification Methods

Purify it as for o-chlorobenzotrifluoride above. 20 1.4432. [Beilstein 5 III 692, 5 IV 814.]
