Sodium silicate from rice husk ash (RHA) was transformed to functionalized silica with 3-(chloropropyl)triethoxysilane (CPTES) via a simple sol–gel technique in a one-pot synthesis. The ²⁹Si MAS NMR of the organo–silica complex (RHACCl) showed the presence of T², T³, Q³ and Q⁴ silicon centers. The ¹³C MAS NMR showed that RHACCl had three chemical shifts at 10.37, 26.70 and 47.69 ppm consistent with the three carbon atoms of the CPTES moiety. The presence of carbon, silicon and chlorine was determined by a combination of elemental analysis and EDX study.

通过简单的一锅合成将3-（氯丙基）三乙氧基硅烷固定在二氧化硅上

通过简单的溶胶-凝胶技术在一锅合成中，将稻壳灰（RHA）中的硅酸钠与3-（氯丙基）三乙氧基硅烷（CPTES）转化为功能化二氧化硅。有机硅配合物（RHACCl）的²⁹ Si MAS NMR显示存在T ²，T ³，Q ³和Q ⁴硅中心。的¹³ ÇMAS NMR显示RHACCl在10.37，26.70和47.69 ppm的与CPTES部分的三个碳原子相一致有三个化学位移。通过元素分析和EDX研究相结合，确定了碳，硅和氯的存在。
