| Abstract: Layered double hydroxides (LDHs) or hydrotalcite-like materials of the type Mg1-xAlx(OH)2(Xn-)x/n·zH2O are most readily prepared when Xn- is the carbonate ion.Although many other LDHs undergo facile ion-exchange reactions, the carbonate ion in LDHs is known to be very difficult to replace by conventional ion-exchange.We have developed a simple synthesis of adipate-pillared LDHs of the type Mg4Al2(OH)12[O2C (CH2)4CO2]·4H2O by direct reaction of free adipic acid with an LDH carbonate precursor.The materials obtained have been characterized by XRD, FT-IR and DTA.It is shown that by appropriate choice of reaction conditions, the carbonate ions in the precursor can be completely replaced by adipate ions.The adipate-pillared LDHs retain a layered structure with an interlayer distance of 1.40nm.The interlayer adipate ions are lost on heating the material to 390℃. | |
