WHITE CRYSTALLINE SOLID??
1,2,3,4-tetrachlorobenzene was used as a model compound to determine the chlorobenzenes (CBs) in soil samples. It was also used for rapid dechlorination of 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TeCDD).??
ChEBI: A tetrachlorobenzene carrying chloro groups at positions 1, 2 , 3 and 4.?? ??
White to off-white crystals.??? ?? ??
Insoluble in water.?? ???
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.????
ACUTE/CHRONIC HAZARDS: 1,2,3,4-Tetrachlorobenzene may cause irritation of the skin.????
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.]1,2,3,4-Tetrachlorobenzene ?? ?? ? ???
