Anwendungen & Verwendung
Beschreibung
Barium acetate (Ba(C2H3O2)2) is the salt of barium (II) and acetic acid.
Verwenden
Barium acetate is used as a mordant for printing textile fabrics, for drying paints and varnishes and in lubricating oil. In chemistry, it is used in the preparation of other acetates; and as a catalyst in organic synthesis.
Herstellung & Synthese
synthetische
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate : BaCO3 + 2 CH3COOH → (CH3COO)2Ba + CO2 + H2O The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used : BaS + 2 CH3COOH → (CH3COO)2Ba +H2S Again, the solvent is evaporated off and the barium acetate crystallized.
