Bromine and hydrogen compounds are strong acids. Slightly smoke. The toxicity is low, with a median lethal concentration (inhalation in rats) of 2.858G/L/h. Long term exposure, manifested as chronic respiratory irritation symptoms and digestive dysfunction. Easy to dissolve in organic solvents such as chlorobenzene and diethylmethane. Can be mixed with water, alcohol, and acetic acid. It has strong corrosiveness and can react with all metals except platinum, gold, and tantalum to form metal bromide. It also has strong reducibility and gradually turns yellow brown when exposed to air and sunlight due to free bromine.
Application area
Hydrogen bromide gas is a widely used gas in organic synthesis, which can be used to synthesize a series of bromine products, such as monomers of nylon 11, dibromomethane, 1-bromopropane β- Bromoethylbenzene, etc. The latter few products are important organic solvents, pesticides, and pharmaceutical intermediates. Previously, due to limitations in the process of synthesizing HBr gas, many intermediates of bromides such as bromopropane β- Bromoethylbenzene and others all use the reaction between alcohol and hydrobromic acid, which has a high cost and requires further treatment of many low concentration waste acids. If the HBr gas and olefin addition method is used, its production cost can be greatly reduced.
1. Measure sulfur, selenium, bismuth, zinc, and iron. Separation of tin from arsenic and antimony, alkylation catalysts, reducing agents, organic synthesis, preparation of organic and inorganic bromides, and high-purity metal extraction.
2. Used to manufacture various bromine compounds, and can also be used in industries such as medicine, dyes, and spices; It is a basic raw material for manufacturing various inorganic bromides such as sodium bromide, potassium bromide, lithium bromide, and calcium bromide, as well as certain alkyl bromides such as bromomethane and bromoethane. Used in medicine to synthesize sedatives and anesthetics. It is also a good solvent for some metal minerals, used for the extraction of high-purity metals.
3. Used as an alkylation catalyst in the petroleum industry. Separating agents for alkoxy and phenoxy compounds, as well as catalysts for the oxidation of alicyclic and chain hydrocarbons to ketones, acids, or peroxides.
4. The pharmaceutical industry is used to synthesize medicinal products such as sedatives and anesthetics.
Highly toxic. Both gases and vapors have a pungent odor that can irritate the eyes and respiratory system. Patients who inhale gas should be evacuated from the contaminated area, placed for rest and kept warm. If eye contamination occurs, rinse with plenty of water. In severe cases, seek medical attention. When skin contamination occurs, rinse with plenty of water first. In severe cases, seek medical attention.
