C60对MCM-41催化作用的研究(英文)
Study on Extraction and Sepration of the Taxol
【摘要】 直接研磨C60和脱除模板剂的MCM-41可以导致前者进入后者的孔道,同时将分子筛孔道内的吸附水挤出.通过原位红外的研究发现,即使在较低真空温度下,载有C60的MCM-41孔道内的硅羟基也可以被除去,表明C60对MCM-41的脱羟基起催化作用.
【Abstract】 Taxol was analyzed by high performance liquid chromatography on a CLC-C8 column using Acetonitrile∶MeOH∶H2O(9∶2∶9) mobile phase and UV(228nm) detector a simple, rapid and accurate method was established. Linear correlation coefficients 0.999l; then variation coefficients were 1.82%, the lowest detetable quantity of taxol could reach 2.00μg.
