| Abstract: | The bentonite in the Longquanshan area of Sichuan was purified and Na-modified by use of Na2CO3,and the organophilic bentonite was prepared by use of hexadecyl-trimethy ammonium bromide.The X-ray diffraction data,the FT-IR diagram and DTA-TG spectra of the sodium modified bentonite and organic bentonite indicate that the sodium-based modification and organobentonite preparation of the bentonite are successful.The best synthesis process for organobentonite preparation is as follows.In 129.6 g/L mineral syrup concentration,CTMAB dosage is 45% of the purified sodium-based bentonite,the reaction temperatures is around 65℃,and the reaction time is 110 min. |
