Barium Hydroxide Monohydrate CAS 22326-55-2

Barium Hydroxide Monohydrate (CAS 22326-55-2) is an inorganic base, a white powder. It dissolves in water to a strong alkaline solution, reacts with fatty acids and takes up CO2 from air, so packs stay sealed. The material makes barium based grease, refines beet sugar, removes sulfate from brines and water and serves barium salt production and synthesis. It is handled as a poisonous barium compound. UATChem supplies industrial grades in 25 kg kraft bags and 1000 kg ton bags, with COA, TDS and SDS on request.

What Barium Hydroxide Monohydrate Is

Barium Hydroxide Monohydrate is the one water form of barium hydroxide, Ba(OH)2.H2O, the usual commercial grade. The white solid is dense, odorless and soluble in water with heat, and exposed material turns to barium carbonate by taking up CO2. A strong base that also carries barium ions, it neutralizes acids, precipitates sulfate and forms barium soaps. UATChem supplies the monohydrate, with assay, carbonate and chloride on the COA and TDS.

Grease, Sugar, Sulfate Removal and Synthesis Uses

  • Barium grease. Reacted with fatty acids it forms barium soaps used in water resistant, extreme pressure lubricating grease.
  • Beet sugar. It refines beet sugar, helping clarify and recover sugar from process liquors.
  • Sulfate removal. It precipitates sulfate as insoluble barium sulfate in brines, boiler water and process water treatment.
  • Barium salts and synthesis. It produces other barium chemicals, acts as a strong base in organic synthesis and supports PVC stabilizer work.

Packaging, Documents and Ordering

  • Orders ship in 25 kg kraft paper bags, and bulk volumes in 1000 kg FIBC ton bags, matching the photos. Keep the solid sealed and dry, away from CO2 and moisture.
  • Under UN 1564 it is handled as a poisonous barium compound, and every lot comes with a COA, TDS and SDS covering assay, carbonate and chloride.
  • Samples are available for evaluation. To quote, UATChem needs the grade, quantity, packing and destination port.

FAQ

Q: What is barium hydroxide monohydrate used for?

A: It makes barium based grease, refines beet sugar, removes sulfate from water and serves barium salt production and synthesis.

Q: How is barium hydroxide monohydrate packed?

A: UATChem supplies the white powder in 25 kg kraft paper bags and 1000 kg FIBC ton bags, with other packing arranged on request.

Q: Why must barium hydroxide be kept sealed?

A: It takes up CO2 from air and turns to barium carbonate, and moisture changes it, so sealed dry storage keeps the grade.

Q: Is barium hydroxide monohydrate hazardous?

A: It is a poisonous barium compound under UN 1564 and a strong base, and every lot has a COA, TDS and SDS for safe handling.
