colorless crystals or white particles or powders. Melting point of 963 deg C; d3. 86. Slightly hygroscopic. Soluble in water, soluble in methanol and glycerol, almost insoluble in ethanol, ethyl acetate, acetone. Toxic chloride and barium oxide fumes are decomposed by heat.
Industrial barium chloride was dissolved in hot water, and 3% barium hydroxide solution and ammonium sulfide solution were added. The mixture was heated to 80-90 °c over 20-30min, placed and filtered. The filtrate was evaporated to a relative density of 1. 33, and the precipitated crystals were filtered off with a Buchner funnel, washed with a small amount of cold water, and dried at room temperature. The pure product barium chloride can be obtained.
Analytical reagents for the determination of selenate, sulfate and platinum. It can also be used in the manufacture of barium salt, water softener, electronics, instrumentation and metallurgical industries.
ICR mice injected intravenously with LDso: 19.2 mg/kg(Ba2). There is a certain toxicity, the intake of products will appear Vomit, Abdominal Pain, Diarrhea and other symptoms, inhalation products, stimulate the nasal cavity, bronchi, lungs and other mucous membranes. Staff should be protected and the workplace should be well ventilated. If the skin and eyes are touched, rinse immediately with running water. Stored in a ventilated, low-temperature, dry place, and stored separately from food.
