实验过程

(EXAMPLE 18) In a similar experiment, 200 g of the ash was mixed with 3.0 L of 20% (v/v) or 21% (w/w) acetic acid. That amount of acetic acid corresponded to 4.2 times the stoichiometric proportion of calcium carbonate in the ash. The slurry was agitated and left overnight at room temperature. 2.7 L of liquid was collected. The liquid collected contained 9.2±0.2% solids (based on two separate measurements), as was 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 6.6% by weight. The elemental calcium content in the dried extract was determined to be 19.2±0.4% (based on two independent measurements), translating into 76% Ca(CH3COO)2, or 85% Ca(CH3COO)2.H2O.
