摘　　要：０前言中孔ＭＣＭ－４１分子筛是Ｍｏｂｉｌ公司１９９２年开发的一种具有２－１０ｎｍ孔径的新型分子筛材料。由于其独特的孔径范围和表面特性，相关研究已经成为国际分子筛研究领域的热点课题，对它的合成、表征和催化作用已进行了许多研究［１～７］。Ｍｏｂｉｌ公司的...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 d 100 >4 nm could be obtained with putting auxiliary alkanes As synthesized samples have been characterized by XRD, SEM and N 2 adsorption The experimental results showed that adding auxiliary alkanes made decreasing order of molecular sieve MCM 41
