• 説明

  Trichlorobenzenes (TCBs) are synthetic chemicals that occur in three different isomeric forms. The three chlorinated cyclic aromatic isomers are 1,2,3-trichlorobenzene (1,2,3-TCB), 1,2,4-trichlorobenzene (1,2,4-TCB), and 1,3,5-trichlorobenzene (1,3,5-TCB). 1,2,4-TCB is one of the 188 chemicals designated as a hazardous air pollutant under the Clean Air Act.

• 化学的特性

  1,2,3-Trichlorobenzene and 1,3,5-trichlorobenzene are colorless solids, while 1,2,4-trichlorobenzene is a colorless liquid. Although the three isomers of trichlorobenzenes have the same molecular weight and formula, they each may have different chemical and toxicological properties. One of the isomers (1,2,4-trichlorobenzene) is produced in large quantities and is used as a solvent to dissolve such special materials as oils, waxes, resins, greases, and rubber. It is also frequently used to produce dyes and textiles. The other two isomers, 1,2,3-trichlorobenzene and 1,3,5-trichlorobenzene, are produced in lower quantities and have fewer uses.

• 使用

  Detoxification by catalytic hydrotreatment of 1,2,3-Trichlorobenzene is used for the disposal of hazardous organic waste liquids. As constituent of trichlorobenzene mixt used for termite control. As transformer fluid, dye carrier & solvent. Solvent for high melting products, Coolant in electrical installations and glass tempering. In polyester dyeing, lubricants, Heat transfer medium. As chemical intermediate for 2,3-dichlorophenol.

• 一般的な説明

  A white solid with a sharp chlorobenzene odor. Insoluble in water and denser than water. Hence sinks in water. Melting point 63-64°C (145-147°F).

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  1,2,3-Trichlorobenzene can react with oxidizing agents. . May emit toxic hydrogen chloride and phosgene gases in fire.

• 健康ハザード

  Inhalation may cause irritation of respiratory tract. Irritating to the eyes. May redden skin on contact. Ingestion may cause liver damage.

• 環境運命予測

  Biological. Under aerobic conditions, soil microbes are capable of degrading 1,2,3- trichlorobenzene to 1,2- and 1,3-dichlorobenzene and carbon dioxide (Kobayashi and Rittman, 1982). A mixed culture of soil bacteria or a Pseudomonas sp. transformed 1,2,3-trichlorobenzene to 2,3,4-, 3,4,5-, and 2,3,6-trichlorophenol (Ballschiter and Scholz, 1980).
  In an enrichment culture derived from a contaminated site in Bayou d’Inde, LA, 1,2,3- trichlorobenzene underwent reductive dechlorination to 1,2- and 1,3-dichlorobenzene at relative molar yields of 1 and 99%, respectively. The maximum dechlorination rate, based on the recommended Michaelis-Menten model, was 60 nM/d (Pavlostathis and Prytula, 2000).
  Photolytic. The sunlight irradiation of 1,2,3-trichlorobenzene (20 g) in a 100-mL borosilicate glass-stoppered Erlenmeyer flask for 56 d yielded 32 ppm pentachlorobiphenyl (Uyeta et al., 1976).
  Chemical/Physical. At 70.0 °C and pH values of 3.07, 7.13, and 9.80, the hydrolysis half-lives were calculated to be 19.2, 15.0, and 34.4 d, respectively (Ellington et al., 1986). Emits toxic chloride fumes when heated to decomposition.
