Ti-HMS催化剂的合成及性能研究

摘要分别用十二胺 (DDA)和十六烷基三甲基溴化铵 (TMAOH)做模板合成了中孔骨轲钛催化剂Ti HMS(HMS为合成的硅氧中孔载体材料类型 )FT IR表征显示催化剂在96 0cm- 1附近有吸收峰 ,且强度与硅钛比成正比。研究了催化剂制备条件对苯乙烯环氧化反应的影响 ,结果表明 :焙烧温度为 6 50℃、活化温度为 2 0 0℃、反应温度 4 5℃～55℃、反应时间 6h ,苯乙烯转化率接近 80 % ,环氧化苯乙烯收率达 70 %。

Abstract： Used lauryl amine,as well as hexadecyl trimethyl ammonium bromide as templating agent,Ti catalysts with mesoporous framework(Ti HMS) were synthesized.FT IR show that there is a weak band near 960 cm -1 ,and the intensity of this band corresponds well with the content of Ti loading.The condition of synthesising the catalysts was systemically researched.Experimetn data show:when calcining temperature is at 650℃,activating temperature at 200℃,reacting temperature between 45 and 55℃,the percent conversion of styrene approach 80% and yield of epoxy styrene get to 70%.
