説明
Barium chloride is a white/colourless solid and stable under ordinary conditions of use
and storage. It is incompatible with bromine trifluoride and 2-furan percarboxylic acid
(anhydrous).
化学的特性
White solid
使用
Barium chloride dihydrate is mainly used in the purification of brine solution in caustic chlorine plants, as a reagent in the test for sulfate ion in chemical lab, and as a cleansing agent in the production of other barium chemicals and lubricating oil additives. It is used in the production of molecular sieves, pigments, and paper coatings, and serves as a precursor to fabricate the doped barium zirconate.
定義
ChEBI: A hydrate that is the dihydrate form of barium chloride.
一般的な説明
White crystalline solid with a bitter, salty taste.
空気と水の反応
Water soluble.
反応プロフィール
Barium chloride dihydrate may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.
健康ハザード
Exposures to barium chloride cause sore throat, coughing, and labored breathing, and
become harmful and fatal if swallowed or inhaled. Prolonged exposures cause irritation
to the skin, eyes, and respiratory tract, and involve the heart, respiratory system, and the
CNS. An accidental ingestion of barium chloride causes severe gastroenteritis, abdomi-
nal pain, vomiting, diarrhea, tremors, faintness, paralysis of arms and legs, and a slow or
irregular heartbeat. In severe cases, barium chloride may cause collapse and death from
respiratory failure.
火災危険
Flash point data for Barium chloride dihydrate are not available. Barium chloride dihydrate is probably combustible.
安全性プロファイル
A poison by intraperitoneal route.When heated to decomposition it emits toxic vapors of Baand Cl
-.
貯蔵
Barium chloride should be kept stored in a tightly closed container. Protect from physi-
cal damage. Store in a cool, dry, ventilated area away from sources of heat, moisture, and
incompatibilities. Containers of this material may be hazardous when empty since they
retain product residues (dust, solids); observe all warnings and precautions listed for the
product.
純化方法
It is crystallised twice from water (2mL/g) and dried in an oven to constant weight. The solubilities of the hydrate (% of anhydrous wt) in H2O are 31.6 at 0o, 35.7 at 20o and 58.7 at 100o.
予防処置
Occupational workers should be careful during handling of barium hydroxide. Workers
should wear impervious protective clothing, including boots, gloves, laboratory coat,
apron, or coveralls, as appropriate, to prevent skin contact. Workers should use chemical
safety goggles or full-face shields. The workplace should maintain an eye-wash fountain
and quick-drench facilities.
