Synthesis and Structural Characterization of Oleic Acid Embedded Layered Magnesium Borate

Abstract:

The organic-inorganic composite of oleic acid embedded layered magnesium borate was synthesized by low temperature hydrothermal method with magnesium chloride (MgCl₂•6H₂O), borax (Na₂B₄O₇•10H2O) as reactants, oleic acid as the embedded agent. The structure and morphologies of the synthesized samples were investigated by X-ray diffraction, N2 adsorption-desorption isotherms, scanning electron microscopy and Fourier transform infrared spectroscopy techniques. The results suggest that the structure of oleic acid embedded magnesium borate is layered-by-layered, and the interlayer spacing was about 6 nm. And the sizes of the lamellar magnesium borate are in the range of 100 nm to 200 nm. The average pore diameter of the prepared product is 22.4 nm. The BET surface area and pore volume are 50.31 m²/g and 0.275 m³/g, respectively. The molecular structure model of oleic acid embedded layered magnesium borate is established.
