실험 절차

A solution of maleic acid was prepared by adding 39.7 g of maleic anhydrideto 80 g of water and heating the mixture to 60°±5° C. over40 minutes. Then a slurry of calcium carbonate filter cake (38.2 g, 0.248 mole calcium carbonate), and water, 40 g, were added to the maleic acid solution at 60°±5° C. over 40 minutes. Carbon dioxide wasstripped off and calcium maleate was formed.

후처리
