1,2,3,5-Tetrachlorobenzene Chemical Properties,Uses,Production

Definition

ChEBI: A tetrachlorobenzene carrying chloro groups at positions 1, 2, 3 and 5.

General Description

White crystals or off-white solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as 1,2,3,5-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. 1,2,3,5-Tetrachlorobenzene may react with oxidizers. .

Health Hazard

ACUTE/CHRONIC HAZARDS: 1,2,3,5-Tetrachlorobenzene may cause irritation on contact.

Fire Hazard

1,2,3,5-Tetrachlorobenzene is probably combustible.

Environmental Fate

Biological. A mixed culture of soil bacteria or a Pseudomonas sp. transformed 1,2,3,5-tetrachlorobenzene to 2,3,4,6-tetrachlorophenol (Ballschiter and Scholz, 1980). The half-life of 1,2,3,5- tetrachlorobenzene in an anaerobic enrichment culture was 1.8 d (Beurskens et al., 1993).
In an enrichment culture derived from a contaminated site in Bayou d’Inde, LA, 1,2,3,5- tetrachlorobenzene underwent reductive dechlorination to 1,2,4- and 1,3,5-trichlorobenzene at relative molar yields of 7 and 93%, respectively. The maximum dechlorination rate, based on the recommended Michaelis-Menten model, was 94 nM/d (Pavlostathis and Prytula, 2000).
Photolytic. Irradiation (λ ≥285 nm) of 1,2,3,5-tetrachlorobenzene (1.1–1.2 mM/L) in an acetonitrile-water mixture containing acetone (0.553 mM/L) as a sensitizer gave the following products (% yield): 1,2,3-trichlorobenzene (5.3), 1,2,4-trichlorobenzene (4.9), 1,3,5-trichlorobenzene (49.3), 1,3-dichlorobenzene (1.8), 2,3,4,4′,5,5′,6-heptachlorobiphenyl (1.41), 2,2′,3,4,4′,6,6′- heptachlorobiphenyl (1.10), 2,2′,3,3′,4,5′,6-heptachlorobiphenyl (4.50), four hexachlorobiphenyls (4.69), one pentachlorobiphenyl (0.64), trichloroacetophenone, 1-(trichlorophenyl)-2-propanone, and (trichlorophenyl)acetonitrile (Choudhry and Hutzinger, 1984). Without acetone, the identified photolysis products (% yield) included 1,2,3-trichlorobenzene (trace), 1,2,4-trichlorobenzene (24.3), 1,3,5-trichlorobenzene (11.7), 1,3-dichlorobenzene (0.5), 1,4-dichlorobenzene (3.3), pentachlorobenzene (1.43), 1,2,3,4-tetrachlorobenzene (5.99), two heptachlorobiphenyls (1.40), two hexachlorobiphenyls (<0.01), and one pentachlorobiphenyl (0.75) (Choudhry and Hutzinger, 1984).

Purification Methods

Crystallise it from EtOH. [Beilstein 5 II 157, 5 III 551, 5 IV 668.]
