Фторбензол химические свойства, назначение, производство
Описание
Fluorobenzene is a colourless, highly flammable liquid, stable and incompatible with oxidising
agents. It is not compatible with oxidising agents such as perchlorates, peroxides,
permanganates, chlorates, nitrates, chlorine, bromine and fluorine, ammonium nitrate,
chromic acid, halogens, and nitric acid. It is used as an insecticide and as a reagent for
plastic and resin polymers.
Химические свойства
Fluorobenzene is a colorless liquid.
Использование
Fluorobenzene is used as a reagent for plastic or resin polymers. It acts as a solvent for highly reactive species. On fluorination of fluorobenzene it gives 1,2-difluorobenzene. It is also used as a material in making medicine.
Определение
ChEBI: The simplest member of the class of monofluorobenzenes that is benzene carrying a single fluoro substituent.
Общее описание
A clear, colorless liquid with a characteristic aromatic odor. About the same density as water. Flash point 5°F. Vapors heavier than air. May irritate the skin, eyes, and mucous membranes. Used as an insecticide, larvacide and as a reagent for plastic or resin polymers.
Реакции воздуха и воды
Highly flammable. Slightly soluble in water.
Профиль реактивности
Incompatible with strong oxidizing agents.
Опасность
Flammable, dangerous fire risk. Irritant.
Угроза здоровью
Irritating to skin, eyes and mucous membranes. Repeated exposure of skin may cause dermatitis due to defatting action. Chronic inhalation of vapors or mist may result to damage to lungs, liver and kidneys. Acute vapor exposures can cause symptoms ranging from coughing to transient anesthesia and central nervous system depression.
Профиль безопасности
: Mddly toxic by
ingestion and inhalation. A very dangerous
fire hazard when exposed to heat, flame, or
oxidizers. To fight fire, use water spray,
mist, foam, dry chemical, CO2. When heated
to decomposition it emits toxic fumes of F-
Возможный контакт
Fluorobenzene is used as an insecti cide and as a reagent for plastic or resin polymers.
Перевозки
UN2387 Fluorobenzene, Hazard Class: 3;
Labels: 3-Flammable liquid.
Методы очистки
Dry fluorobenzene for several days with P2O5, then fractionally distil it. [Beilstein 5 H 198, 5 IV 632.]
Несовместимости
Vapor may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, perox ides, permanganates, perchlorates, chlorine, bromine, fluo rine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides.
