Synthesis and Performance of Functionalized α-Zirconium Phosphate Modified with Octadecyl Isocyanate

الملخص EN

The α-zirconium phosphate (α-ZrP) and hydrophobically modified α-zirconium phosphate (α-ZrP-I) were prepared.

The grafting of octadecyl isocyanate was confirmed by Fourier transform infrared (FTIR) spectra, X-ray diffraction (XRD), and thermogravimetric analysis (TGA).

The dispersion of α-ZrP-I was studied by environmental scanning electron microscopy (SEM).

The wettability of α-ZrP-I was determined by Kruss DSA30.

Then, the effects of decompression and augmented injection of α-ZrP-I have been studied.

The results of water flooding experiments show that the appropriate concentration of α-ZrP-I has an effect on the decrease of the water injection pressure.
