Nature
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.
Preparation Method
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.
Use
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.
Safety
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.

| Introduction | barium chloride dihydrate is an important inorganic chemical raw material, which is an important intermediate raw material for the preparation of barium salt and other materials, with the rapid development of electronics and information industry and the recovery of European economy, the demand for barium chloride dihydrate is increasing in quality and quantity. Barium chloride dihydrate has a wide range of uses, which can be used as analytical reagent, dehydrating agent, insecticide, purifying agent, mordant for printing and dyeing, matting agent for rayon, it can also be used as a heating medium for high temperature heat treatment and metal processing in the mechanical industry. |
| toxicity | chlorination lock is a highly toxic drug. Can cause inflammation of the brain and pia mater. Poisoning increased capillary permeability, accompanied by bleeding and edema; Inhibition of bone marrow and cause liver disease, spleen sclerosis. Oral poisoning caused by stomach pain, Nausea, Vomit, Diarrhea, elevated blood pressure, pulse solid and irregular, Dyspnea. Ingestion of 0.2~0.8g can cause poisoning, and the lethal dose is 0.9 ~ g. If found poisoning, quickly take magnesium sulfate or sodium sulfate, take gastric lavage, enema, emetic and other measures. The maximum allowable concentration in the United States is 0 5 mg/m3. Attention should be paid to dust and dust in the production process. Work should wear masks, gloves, and work clothes to protect the skin and respiratory organs. |
| Use | used in water purification, tanning, textile, ceramic and other industries, also used in the manufacture of other barium salts and metal heat treatment, etc. mainly used in metal heat treatment, barium salt manufacturing, electronic instruments, and used as water softener is the raw material for the manufacture of barium salt. It can be used as an insecticide to control a variety of plant pests. Brine and boiler water used for refining caustic soda by electrolysis. It is also used for the preparation of pigments. The textile and leather industries are used as mordant and rayon Matting agents. The machinery industry is used for quenching and metal processing. used in water purification, tanning, pigment, textile, ceramic and other industries, also used in the manufacture of other barium salts and metal heat treatment used as analytical reagents and dehydrating agents used as analytical reagents and water softeners, also for the production of barium salt determination of sulfate and selenate etc. Water softener. Fabric dyeing determination of sulfate and selenate, chromatography analysis, drop analysis determination of platinum, soft water agent. Fabric dyeing. |
| production method | hydrochloric acid method barium sulfide solution (see barium sulfide for preparation) is reacted with hydrochloric acid, and then desulfurized, neutralized, evaporation, cooling crystallization, centrifugation, drying. Finished barium chloride dihydrate was obtained. Its BaS 2HCl 2H2O → BaCl2 · 2H2O H2S-calcium chloride method reacts barite with pulverized coal and calcium chloride aqueous solution, and hydrochloric acid is added after leaching for desulfurization, followed by evaporation and concentration, cooling crystallization, centrifugal dehydration, dry, that is, barium chloride dihydrate products. This method can also be prepared by anhydrous barium oxide. The BaSO4 4C CaCl2 2H2O → BaCl2 · 2H2O CaS 4CO chloride method is used to leach the barium sulfide melt with water, and then the obtained 170g/L barium sulfide solution is chlorinated at 85~90 ℃, the barium chloride product was obtained. Its BaS Cl2 → BaCl2 S Witherite-hydrochloric acid method the Witherite powder is added into the reactor containing water, and the reaction is carried out by adding hydrochloric acid at about 70 ℃ under stirring, filtering and washing with hot water, the filtrate was concentrated by evaporation, cooled and crystallized, and centrifuged. Finished barium chloride dihydrate was obtained. Its BaCO3 2HCl H2O → BaCl2 · 2H2O CO2 |
