Applications of Barium Hydroxide include:
- chemistry:
- analytical chemistry: titration of weak acids, particularly organic acids (the clear aqueous solution is free of carbonate as Barium Carbonate is insoluble in water)
- organic chemistry: as a strong base (for instance, hydrolysis of esters and nitriles, decarboxylation of amino acids and preparation of cyclopentanone, diacetone alcohol and D-Gulonic γ-lactone)
- to neutralize sulfuric acid solutions
- to synthetize other Barium compounds
- to clean up acid spills
- water treatment: complete removal of sulphate ions
- manufacture of glass
- manufacture of ceramics
- to make lubricating and oil additives: internal combustion engine lubricating oil additives, barium-based grease and oil refining performance additives
- beet sugar
- resin stabilizer
- may initiate polymerization reactions in polymerizable organic compounds, especially epoxides
