実験手順
A solution of maleic acid was prepared by adding 39.2 g of maleic anhydrideto 40 g of water and heating the mixture to 70° C. in a water bath to form a solution of maleic acid. A calcium carbonate filter cake (23.4 g, 0.248 mole calcium carbonate) and 1 g of calcium carbonate was added tothe maleic acid solution at 70° C. and heated for 50 min. Carbon dioxide was stripped off and calcium maleate was formed.
