4-Хлор-о-фенилендиамин химические свойства, назначение, производство
Химические свойства
4-Chloro-o-phenylenediamine is a brown crystalline powder or leaflets from water; freezing/melting point 67-73°C; also reported in lit. @ 76°C. Slightly soluble in water. soluble in benzene, very soluble in ethanol, ether.Использование
4-Chloro-o-phenylenediamine can be used as an oxidation base for dye preparation, as a chemical intermediate to produce 5-chlorobenzotriazole, as a curing agent for epoxy resins, as a reagent in gas chromatography, and to synthesize experimental pharmaceuticals. It has been used as a chemical intermediate in dye production and was patented as a hair-dye component, but there is no evidence that it is currently used in the United States for these purposes (IARC 1982, HSDB 2009).Определение
ChEBI: 4-Chloro-ortho-phenylenediamine is a member of monochlorobenzenes. Undergoes cyclizations and cyclocondensations to form benzimidazoles.Методы производства
Commercial production of 4-chloro-o-PDA in the United States was first reported in 1941. About 0.45–4.5 thousand kg was produced by a U.S. company in 1977. It was also produced by one company in the Federal Republic of Germany. This compound has been patented as a hair dye component, fur dyes, inks, and hair coloring formulations, and is believed to be used to produce 5-chlorobenzotriazole, an isomer of which is a photographic chemical.The primary routes of potential human exposure to 4- chloro-o-PDA are inhalation and dermal contact during its production. Consumer exposure may occur from use of hair dyes or products made from 5-chlorobenzotriazole.
Общее описание
4-chloro-o-phenylenediamine appears as brown crystalline solid or powder. (NTP, 1992)Реакции воздуха и воды
4-Chloro-1,2-diaminobenzene may be sensitive to prolonged exposure to air and light. Insoluble in water.Профиль реактивности
4-Chloro-1,2-diaminobenzene is incompatible with strong oxidizers. 4-Chloro-1,2-diaminobenzene reacts with alpha-ketoacids to form quinoxalones.Пожароопасность
Flash point data for 4-Chloro-1,2-diaminobenzene are not available. 4-Chloro-1,2-diaminobenzene is probably combustible.Профиль безопасности
Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Human mutation data reported. When heated to decomposition it emits toxic fumes of Cland NOx. See also AROMATIC AMINES.Возможный контакт
This organochlorine material has been patented as a hair dye component. It is believed to be used in production of photographic chemicals. In varying degrees, organochlorines are absorbed from the gut and also by the lung and across the skin.Канцерогенность
4-Chloro-o-phenylenediamine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity fromstudies in experimental animals.Перевозки

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Light sensitive. It reacts with alpha-ketoacids to form quinoxalones or benzopyrazines.Утилизация отходов
Disposal of unused product must be undertaken by qualified personnel who are knowledgeable in all applicable regulations and follow all pertinent safety precautions including the use of appropriate protective equipment. For proper handling and disposal, always comply with federal, state, and local regulations.4-Хлор-о-фенилендиамин запасные части и сырье
