    摘要： The invention refers to a process to separate silicates and alkaline earth metal carbonates implementing at least one hydrophobically modified polyalkyleneimine, wherein: i) the polyalkyleneimine is hydrophobically modified by replacement of all or part of the hydrogens of their primary and/or secondary amino groups by functional group R, where R comprises a linear or branched or cyclic alkyl and/or aryl group and contains 1 to 32 carbon atoms; ii) prior to modification, the polyalkyleneimine has at least 3 alkyleneimine repeat units and a molecular weight of between 140 and 100 000 g/mol; iii) modification of the polyalkyleneimine results in an increase in the atomic C amount, relative to the unmodified polyalkyleneimine, of between 1 and 80%. The invention additionally refers to a silicate-containing product and an alkaline earth metal carbonate-containing product obtained by the process of the invention, and to their uses.

    摘要翻译： 本发明涉及分离实施至少一种疏水改性的聚亚烷基亚胺的硅酸盐和碱土金属碳酸盐的方法，其中：i）聚亚烷基亚胺通过其主要和/或仲氨基的全部或部分氢的置换来疏水改性， 官能团R，其中R包含直链或支链或环状烷基和/或芳基并含有1至32个碳原子; ii）在改性之前，聚亚烷基亚胺具有至少3个亚烷基亚胺重复单元，分子量为140至100000g / mol; iii）聚亚烷基亚胺的改性导致相对于未改性聚亚烷基亚胺的原子C量的增加为1至80％。 本发明还涉及通过本发明的方法获得的含硅酸盐的产品和含有碱土金属碳酸盐的产品及其用途。
