Calcium Bromide Anhydrous Cas No: 7789-41-5

Calcium bromide anhydrous is a chemical compound with the formula CaBr2 It is the anhydrous waterfree form of calcium bromide This inorganic salt is commonly used in various industrial applications including in drilling fluids for the oil and gas industry as a desiccant drying agent and in some chemical processes Heres a description of calcium bromide anhydrous

Appearance Calcium bromide anhydrous is typically a white crystalline solid It is often available in the form of small colorless to white granules or powder

Chemical Formula CaBr2

Molar Mass Approximately 19989 gramsmol

Odor Calcium bromide anhydrous is generally odorless

Solubility It is highly soluble in water meaning it readily dissolves in water to form a clear solution This property makes it useful in various applications where a soluble bromide source is needed

Hygroscopicity Like many bromide salts calcium bromide anhydrous is hygroscopic meaning it has a strong tendency to absorb moisture from the surrounding environment This property makes it useful as a desiccant for drying gases and liquids

Melting Point The melting point of calcium bromide anhydrous is around 730 degrees Celsius 1346 degrees Fahrenheit

Uses

1 Oil and Gas Industry Calcium bromide anhydrous is primarily used as a key component in drilling fluids especially in the oil and gas industry It is added to drilling muds to increase their density which helps control well pressure and prevent blowouts during drilling operations The brine solutions containing calcium bromide also have good compatibility with drilling equipment

2 Desiccant Due to its hygroscopic nature calcium bromide anhydrous is used as a desiccant in various applications It can be used to absorb moisture from gases solvents and other liquids

3 Chemical Processes Calcium bromide anhydrous may be used in some chemical reactions and processes where a soluble bromide source is required

4 Medicine In the past calcium bromide was used in medicine as a sedative and anticonvulsant but it has largely been replaced by other compounds with fewer side effects

Its important to handle calcium bromide anhydrous with care especially when working with it in industrial settings as it can be corrosive and may have specific safety and environmental regulations associated with its use Proper precautions should be taken to ensure safe handling and storage
