Is there any information on the production of barium chloride in the forum?
Reply #22009-02-12
The method for industrial production of BaCl2 is as follows: 1. Reaction of barite with C at 1173K-1473K: BaSO4+4C=BaS+4CO↑ BaSO4+4CO=BaS+4CO2 2. Leaching the product with water: 2BaS+2H2O=Ba(HS)2+Ba(OH)2 3. Pour in CO2 to acidify the solution: Ba(HS)2+CO2+H2O=BaCO3↓+2H2S 4. Finally produced (of course it requires evaporation and crystallization): BaCO3+2HCl=BaCl2+H2O+CO2↑
