Basic information
Physical Properties
Appearance and properties :White Powder
The molecular weight : 171.35
Melting point : 350℃, decomposition into Barium Oxide above temperature 600℃ .
1)Crystalline hydrate
Ba(OH)₂·8H₂O molecular weight 315.47, for colorless monoclinic crystal, relative density 2.18, dissolution point 78℃, boiling point: 780℃, heating water loss into anhydrous barium hydroxide. Both are poisonous.
2)Solubility
Most alkali insoluble in water, Barium Hydroxide is one of the alkalis which is soluble in water. Barium Hydroxide solids placed in the air are extremely prone to deliquescence and then combines with carbon dioxide to form Barium Carbonate and water.The solubility at 20°C is 3.89g in 100g water.
Density : The relative density (water =1)2.18 (16℃) and is stable
3)Danger tags
13(toxic ) ; 2NH4CL + Ba(OH)₂= BaCL₂ +2NH3↑+2H₂O

Preparation of Industrial Hydroxide
Barium Hydroxide,Octahydrate
1)Barium Carbonate reaction with Hydrochloric Acid.
The clear liquid was cooled under 25℃ under constant agitation, crystallized, washed with cold water, centrifuged, and dried to obtain the Barium Hydroxide product.its
BaCO3 + 2 HCL → BaCl2 + CO2 + H2O
BaCl2+2NaOH + 8H2O → Ba (OH) 2 · 8 H2O+ 2NaCl
2)The Barium Chloride method
Takes the mother liquor of Barium Chloride as raw material to react with caustic soda, and then the product is obtained by cooling crystallization and filtration separation.its
BaCl2+2NaOH + 8H2O → Ba (OH) 2 · 8 H2O+ 2NaCl
3)The Barolite method
Crush the ore of Barolite and calcine it. The product is obtained by leaching, filtration, purification, crystallization, dehydration and drying.
BaCO3 → BaO + CO2
BaO + 9H2O→ Ba (OH) 2 · 8H2O
Barium Hydroxide,Monohydrate
Dehydrate the Barium Hydroxide,Octahydrate which is prepared from Barium containing raw material (Barite or Barolite) was under the conditions of vacuum degree 73.3 ~ 93.3kPa and temperature 70 ~ 90℃ for 60 ~ 90min.
Applications
1)It is mainly used as the additive for the lubricant of internal-combustion engine. It is a kind of superfinish multi-purpose additive for barium-based grease and oil.
2)Used as a catalyst for the synthesis of phenolic resin.
The condensation polymerization reaction is easy to control, the prepared resin viscosity is low, the curing speed is fast, the catalyst is easy to remove.The reference dosage is 1% ~ 1.5% of phenol.
3)Used as a catalyst for water-soluble urea modified phenol – formaldehyde adhesive. The cured product is pale yellow. The residual barium salt in the resin does not affect the dielectric property and chemical stability.
4)Used as an analytical reagent
Used in the separation and precipitation of sulphate and the manufacture of barium salts,It is suitable for organic synthesis and other barium salt fabrication.
5)Determination of carbon dioxide in the air.
6)Quantification of chlorophyll.
7)It can also be used for beet sugar fabrication and medicine. Refining of sugar and animal and vegetable oils.
8)Used as Boiler water cleaner; demineralized water.
9)Used as Pesticides.
10)It can be also used in rubber industry,glass and porcelain enamel industries.
