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
white to beige crystalline powder
使用
1,3,5-Trichlorobenzene is used for someof these
applications plus as a termite preparation and insecticide.
These compounds are found as unintended by-products of
the manufacture of the mono- and dichlorobenzenes.
一般的な説明
White to off-white crystals.
空気と水の反応
Insoluble in water.
反応プロフィール
Can react vigorously with oxidizing materials. .
火災危険
1,3,5-Trichlorobenzene is combustible.
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes.
Mutation data reported. When heated to
decomposition it emits toxic vapors of Cl-.
環境運命予測
Biological. Under aerobic conditions, soil microbes degraded 1,3,5-trichlorobenzene to 1,3- and
1,4-dichlorobenzene and carbon dioxide (Kobayashi and Rittman, 1982). A mixed culture of soil
bacteria or a Pseudomonas sp. transformed 1,3,5-trichlorobenzene to 2,4,6-trichlorophenol
(Ballschiter and Scholz, 1980).
In an enrichment culture derived from a contaminated site in Bayou d’Inde, LA, 1,3,5-
trichlorobenzene underwent reductive dechlorination yielding 1,3-dichlorobenzene. The maximum
dechlorination rate, based on the recommended Michaelis-Menten model, was 9.5 nM/d
(Pavlostathis and Prytula, 2000).
Photolytic. The sunlight irradiation of 1,3,5-trichlorobenzene (20 g) in a 100-mL borosilicate
glass-stoppered Erlenmeyer flask for 56 d yielded 160 ppm pentachlorobiphenyl (Uyeta et al.,
1976). A photooxidation half-life of 6.17 months was reported for the vapor-phase reaction of
1,3,5-trichlorobenzene with OH radicals (Atkinson, 1985).
純化方法
Recrystallise it from dry *benzene or toluene. [Beilstein 5 IV 666.]
