Mg-Al layered double hydroxides containing carbonates and nitrates in theinterlayer gallery were used as parent materials for anion exchange. NO-3 and CO2-3 anions were exchanged with oxoanions containing vanadium, chromium, molybdenum and tungsten. Ion-exchange in basic solution led to introduction of V2O 4-7, CrO2-4, MoO2-4 and WO2-4 anions, while V10O286-, Cr2O2-7, Mo7O6-24 and W7O6-24 forms were intercalated in acidic solution. The intercalation was confirmed by X-ray diffraction and FTIR spectroscopy. Oxidative dehydrogenation of n-butane was carried out over hydrotalcite-derived catalysts. The catalysts obtained by thermal decompn. of V2O4-7-contg. Hydrotalcites appeared to be the most active ones in a prodn. of 1,3-butadiene. However, the highest yield of butenes was achieved over Mg-Al-Cr oxides catalyst in the low temp. range (Ł550C).
