| 总结: | <abstract language="eng">Brucite (Mg(OH)2) is a structural model of several natural layered minerals as well as of synthetic layered double hydroxides (LDH). Exchange reaction studies of these compounds are well documented in the literature but surface chemical modifications, especially for brucite, are quite rare. We report the behaviour of brucite in reaction with succinic and benzoic acid in different solvents and temperatures. The compounds were analysed through X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The surfaces of brucite crystals were grafted producing expansions, attributed to the arrangement of the grafted species between the layers. |
