Barium(2+) dichloride

Barium(2+) dichloride is an inorganic salt compound with the chemical formula BaCl2 and CAS number 10361-37-2. It consists of one barium cation and two chloride anions, forming a white crystalline solid with a molecular weight of 208.23 g/mol. This chemical compound is classified as a toxic substance under GHS regulations, requiring careful handling and appropriate safety measures in industrial and laboratory applications.

Barium(2+) dichloride is a white crystalline solid that is highly soluble in water and exhibits hygroscopic properties, meaning it readily absorbs moisture from the air. The compound is odorless and has a density of approximately 3.9 g/cm³. It melts at around 962°C and is also soluble in methanol but insoluble in ethanol and acetone. The substance forms dihydrate crystals under normal atmospheric conditions.

Barium(2+) dichloride is primarily used in the manufacturing of pigments, particularly barium sulfate for paints and coatings. It serves as a precursor for other barium compounds in chemical synthesis and is utilized in the production of specialty glasses and ceramics. The compound also finds applications in metallurgy for case hardening steel, in the textile industry for mordanting fabrics, and in analytical chemistry as a reagent for sulfate precipitation.

Barium(2+) dichloride must be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection due to its Acute Tox. 3 and Acute Tox. 4 classifications. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Avoid skin and eye contact, and never eat, drink, or smoke while handling. Always wash hands thoroughly after use and ensure emergency procedures are readily available.

Barium(2+) dichloride should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Keep containers tightly closed to prevent moisture absorption due to its hygroscopic nature. Store away from food, beverages, and animal feed. Ensure storage areas are equipped with appropriate spill containment measures and maintain temperatures below 40°C to prevent degradation or unwanted reactions.

In case of skin contact with barium(2+) dichloride, immediately remove contaminated clothing and wash the affected area with plenty of water for at least 15 minutes. For eye contact, rinse thoroughly with water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a poison control center or physician for all exposure incidents.

Barium(2+) dichloride must be disposed of as hazardous waste according to local, national, and EU regulations due to its toxic classification. Contact licensed waste disposal companies specializing in toxic chemical waste. Never dispose of this substance in regular trash, sewers, or water systems. Small quantities should be neutralized and precipitated by qualified personnel before disposal. Always consult local environmental authorities for specific disposal requirements and approved waste treatment facilities.

Barium(2+) dichloride is classified under ADR Class 6.1 (Toxic substances) Packing Group III for transportation. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Drivers must hold ADR certification for Class 6.1 substances. Vehicles should carry appropriate emergency equipment and spill kits. Ensure packages are properly secured, labeled with UN numbers, and accompanied by transport documents including safety data sheets and emergency response information.

Barium(2+) dichloride is subject to EU REACH regulation requiring registration for commercial use and CLP regulation for classification and labeling as Acute Tox. 3 and 4. It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with workplace exposure limits, provide safety training, and maintain safety data sheets. Some countries may have additional restrictions on its use, storage, or disposal, requiring consultation with local regulatory authorities.
