Общее описание
Clear colorless liquid.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
Simple aromatic halogenated organic compounds, such as 4-Chlorobenzotrichloride , 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.
Угроза здоровью
ACUTE/CHRONIC HAZARDS: Corrosive; Lachrymator.
Пожароопасность
Flash point data for 4-Chlorobenzotrichloride are not available, however, 4-Chlorobenzotrichloride is probably combustible.
Профиль безопасности
Suspected carcinogen.
A poison by inhalation. Moderately toxic by
ingestion and skin contact. When heated to
decomposition it emits toxic vapors of Cl-.
Возможный контакт
Used in agrochemicals manufacture as
an intermediate; reaction with HF yields chlorobenzotrifluoride as a major intermediate for several pesticides;
for making pharmaceuticals; UV absorbers, and dyestuffs.
This chemical is manufactured in high volume (exceeds 1
million pounds per annum) in the United States.

UN1760 Corrosive liquids, n.o.s., Hazard class:
8; Labels: 8-Corrosive material, Technical Name Required.
Несовместимости
A halogenated aromatic compound.
Hydrolyzes to hydrochloric acid and benzoic acid in all
forms of moisture. Incompatible with strong oxidizers
(chlorates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from reducing agents, alkaline
materials, strong acids, strong bases, amines, nitrides, azo/
diazo compounds, alkali metals, and epoxides.
