ALPHA-BROMOSTYRENE - Introduction
Α-Bromostyrene is an organic compound with the chemical formula C8H7Br. It is a colorless liquid with a strong pungent odor at room temperature. The compound has a density of 1.367 g/cm ^ 3, a boiling point of 228-230°C and a flash point of 82°C.
α-Bromostyrene has a wide range of applications. It helps in the synthesis of many important organic compounds, such as dyes, fluorescent coatings and synthetic resins (polystyrene). It is also used as an intermediate in drug synthesis.
A common method of preparing α-bromostyrene is by reacting styrene with bromine. The reaction is typically carried out under an inert atmosphere with the addition of bromine in an organic solvent such as toluene, followed by the addition of a catalyst such as diphenyldiethyltin, and the reaction temperature is typically carried out at room temperature.
For safety information, α-Bromostyrene is irritating and may be harmful to the eyes, skin and respiratory system. Wear appropriate protective equipment such as goggles, gloves and respirators. Breathing of its vapors or contact with the skin should be avoided. Pay attention to its flammability during use or storage, and avoid contact with oxidants and strong acids. In the event of spills or accidents, appropriate clean-up measures should be taken and relevant chemical handling procedures should be followed.
