Production of calcium carbonate with surface subjected to reactive processing and it application |
| abstract |
FIELD: process engineering. n SUBSTANCE: this invention can be used for production of paper, plastics and dyes. Proposed method comprises provision of calcium carbonate, provision of acid in amount of 5-50 wt % per calcium carbonate mass with pK a smaller than or equal to 2.5; provision of gaseous CO 2 , provision of at least one water-soluble non-polymer organic and/or inorganic weak acid and/or acid salt of said at least one water-soluble non-polymer organic and/or inorganic weak acid. Then, calcium carbonate is brought in contact with at least acid with pK a smaller than or equal to 2.5; provision of gaseous CO 2 , provision of at least one water-soluble non-polymer organic and/or inorganic weak acid and/or acid salt of said at least one water-soluble non-polymer organic and/or inorganic weak acid. Note here said water-soluble non-polymer organic and/or inorganic weak acid features pK a larger than 2.5 while anion of appropriate acid can form water-insoluble calcium salts. n EFFECT: controlled particle size, higher specific surface and yield. n 23 cl, 7 tbl, 7 ex |
