【Abstract】 Organic bentonite was prepared through sodium version and treated with quaternary ammonium salt, taking natural bentonite as raw material.The major factors on synthetic process of the organic bentonite such as pH value, reaction time and temperature,adding quantity of quaternary ammonium salt, were discussed and the optimum coversion conditions were obtained. The product of organic bentonite was analyzed by means of FT-IR and its dispersibility was tested. The results show that natural bentonite could be converted into organic bentonite under optimum conversion conditions.更多还原
