바륨 클로라이드 디하이드레이트 C화학적 특성, 용도, 생산
개요
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).화학적 성질
White solid용도
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.정의
ChEBI: A hydrate that is the dihydrate form of barium chloride.일반 설명
White crystalline solid with a bitter, salty taste.공기와 물의 반응
Water soluble.반응 프로필
Barium chloride dihydrate may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.건강위험
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.화재위험
Flash point data for Barium chloride dihydrate are not available. Barium chloride dihydrate is probably combustible.Safety Profile
A poison by intraperitoneal route.When heated to decomposition it emits toxic vapors of Baand Cl-.저장
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.Purification Methods
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.주의 사항
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.바륨 클로라이드 디하이드레이트 준비 용품 및 원자재
