Diamond Hazard Value Description
1
0 0
Health   0 Poses no health hazard, no precautions necessary and would offer no hazard beyond that of ordinary combustible materials
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

1,2,3,4-Tetrachlorobenzene Chemical Properties,Uses,Production

Chemical Properties

WHITE CRYSTALLINE SOLID

Uses

Component of dielectric fluids, synthesis.

Definition

ChEBI: A tetrachlorobenzene carrying chloro groups at positions 1, 2 , 3 and 4.

General Description

White to off-white crystals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as 1,2,3,4-Tetrachlorobenzene, 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: 1,2,3,4-Tetrachlorobenzene may cause irritation of the skin.

Fire Hazard

1,2,3,4-Tetrachlorobenzene is probably combustible.

Safety Profile

Moderately toxic by ingestion. An experimental teratogen. Experimental reproductive effects. Irritant. Combustible liquid. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, AROMATIC.

Purification Methods

Crystallise it from EtOH. [Beilstein 5 H 204, 5 II 156, 5 III 550, 5 IV 667.]
