摘要：研究了肼插层茂名高岭土时 ,肼在水溶液中的浓度对插层速率的影响 .发现存在着进行插层反应的最低浓度阈值和最佳浓度值 .高浓度肼溶液 (≥ 2 4mol/L)插层高岭土时 ,除扩展的层间距 1 .0 4nm外 ,还出现一个 0 .97nm的新层间距 .红外光谱研究表明 ,此层间距很可能与NH2
The effect of hydrazine concentration on the intercalation rate is investigated as the Maoming kaolinite is intercalated by hydrazine. It has been found that there exist a low threshold and optimized value of hydrazine concentration for the kaolinite intercalation. In addition to the common space 1.04 nm, a new interlayer space distance 0.97 nm, was observed when the kaolinite was intercalated by high concentration hydrazine (≥24 mol/L). The appearance of such new space is attributed to keying of the —NH 2 moiety of hydrazine into the siloxane ditrigonal cavity, according to infrared spectroscopy.
