Intercalation of n-C₁₂H₂₅NH₂ into layered titanate with the aid of microwave radiation

Synthesis of layered tetratitanate-n-C₁₂H₂₅NH₂ intercalation compounds under microwave radiation was reported in this paper. Under microwave radiation, conversion of K₂Ti₄O₉ to H₂Ti₄O₉ in 1 M HCl solution needs only 1 h with 0.88 nm of interlayer distance, and the intercalation of n-C₁₂H₂₅NH₂ could be achieved in 3 h. The formations of the layered hydrogen tetratitanate and the intercalation compounds were confirmed by X-ray diffraction, elemental, thermal gravimetric and differential scanning calorimetric analyses. The interlayer distance of the composite material could expand to 3.92 nm after the intercalation. High power of microwave is favorable during the intercalation of n-C₁₂H₂₅NH₂ into the layered hydrogen tetratitanate.
