    Synthesis

    Anhydrous calcium bromide is made by dehydration (250°C, vacuum) of the hxahydrate CaBr2.6H2O [13477-28-6].

    A white or nearly white, granules, very deliquescent. Odourless; taste sharp, saline and bitter. Soluble in water and in alcohol. It melts and decomposes at red heat with evolution of bromine. It is prepared by neutralizing calcium carbonate with hydrobromic acid or by the action of calcium - hydroxide on solution of iron bromide. Contains not less than 95 per cent and not more than the equivalent of 102 per cent of CaBr2 with reference to the substance dried at 105° to a constant weight.
