zinc bromide usage and synthesis
chemical properties white hygroscopic powder
usage optimal catalyst for stereospecific and regioselective reaction of silacyclopropanes with carbonyl compounds.1
general description a white crystalline noncombustible solid. the primary hazard is the threat to the environment. immediate steps should be taken to limit its spread to the environment. zinc bromide is used in medicine, in photography.
air & water reactions hygroscopic. water soluble
reactivity profile acidic inorganic salts, such as zinc bromide, are generally soluble in water. the resulting solutions contain moderate concentrations of hydrogen ions and have ph's of less than 7.0. they react as acids to neutralize bases. these neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. they usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. many of these compounds catalyze organic reactions.
health hazard inhalation of dust may irritate nose and throat. ingestion can cause irritation or corrosion of the alimentary tract; if large amount is swallowed and not thrown up, drowsiness and other symptoms of bromide poisoning may occur. contact with eyes or skin causes irritation.
