If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

용도

As humectant, in air-conditioning systems. An aqueous solution of lithium bromide containing about 50 % lithium bromide is used as an absorbent in large-scale absorption air conditioning equipment. Lithium bromide is also used in limited amounts by the pharmaceutical industry for dehydrobromination of organic compounds to form olefins.

일반 설명

LiBr/Chlorotrimethylsilane reagent participates in the conversion of alcohols to bromides.

제조 및 합성 방법

제조 방법

Lithium bromide may be prepared by the reaction of lithium hydroxide monohydrate or lithium carbonate with hydrobromic acid. The resultant solution of lithium bromide may be evaporated and cooled to crystallize a hydrate of lithium bromide, the composition of which depends on the final temperature. The lithium bromide hydrate may be filtered from the mixture and carefully dried by the application of heat in a vacuum desiccator to avoid melting the hydrate.
