不同硅铝比Al-MCM-41介孔分子筛的表征及催化合成氯乙酸正辛酯OA北大核心CSCDCSTPCD
Characterization and catalysis performance of mesoporous molecular sieve Al- MCM- 41 with different Si/Al ratio
以十六烷基三甲基溴化铵( CTAB)为模板剂,正硅酸乙酯(TEOS)为硅源,乙二胺为碱性介质,当n(TEOS)∶n( NaAl02)∶n(CTAB)∶n(H2NCH2CH2NH2)∶n(H2O)=1∶x∶0.12∶ 3.5∶130,其中x=0.1,0.033,0.02,0.01,0.006 7时,水热法合成了Al - MCM - 41介孔分子筛.通过XRD,N2吸附-脱附,NH3 - TPD和TEM等手段对不同硅铝比(n(Si)/n(Al))的A…查看全部>>
Mesoporous molecular sieve MCM -41 containing Si and Al with Si/Al molar ratio equal to 10,30, 50,100 and 150 were synthesized under hydrothermal conditions using cetyltrimethylammonium bromide (CTAB) as template and tetraethylorthosilicate (TEOS) as silica source and ethylenediamine as alkaline medium. The optimum molar ratio was n(TEOS): n{ NaA102) : n( CTAB) : n( H2NCH2CH2NH2): n( H20) = 1: x: 0. 12: 3. 5: 130, where x = 0. 1,0. 033 ,0. 02,0. 01 and 0. 00…查看全部>>
