HCID 6116Calcium Acetate

Procedure

(EXAMPLE 17) 200 g of the ash was mixed with 1.8 L of 20% (v/v) or 21% (w/w) acetic acid. That amount of acetic acid corresponded to 2.5 times the stoichiometric proportion of calcium carbonate in the ash. The slurry was agitated and left overnight at room temperature. The liquid collected contained 14.0% solids, as shown by evaporation of a 10-mL sample at 105° C. The theoretical amount of calcium acetate, formed in the reaction mixture, would have been 10.9% solids. The elemental calcium content in the dried extract was determined to be 19.6±0.8% (based on four independent measurements), translating into 77% Ca(CH3COO)2, or 86% Ca(CH3COO)2.H2O.
