Reaction Steps
In a vessel, the following liquid (A) was prepared by adding and mixing 32 kg of water, 8 kg of Ca(OH)2 and 9.8 kg of lactic acid 88%. This liquid was kept at 80° C. in order to keep the calcium lactate dissolved and was continuously stirred to keep the excess Ca(OH)2 suspended. In an other vessel a citric acid solution was prepared by adding and mixing 50 kg of citric acid monohydrate and 32 kg of water.
