| Abstract: By using cetyltrimethylammonium bromite (CTAB) as template, influences of auxiliary alkanes (n-hexane, n-heptane, iso-octane, and petroleum ether) for synthesizing mesoprours molecular sieve MCM-41 with more than 4 nm pore have studied in hydrothermal system. It was proved by experiments that molecular sieve MCM-41 with d100>4 nm could be obtained with putting auxiliary alkanes. As-synthesized samples have been characterized by XRD, SEM and N2 adsorption. The experimental results showed that adding auxiliary alkanes made decreasing order of molecular sieve MCM-41. |
