摘    要:通过简单的一锅两步法制备了三氟金属(铝,钛,锆)接枝介孔SBA-15 (AlTf/S,TiTf/S,ZrTf/S)固体酸材料,并通过XRD,N2吸附,TGA,FTIR,原位吡啶FTIR和元素分析对这些材料进行了详细的表征.其中,ZrTf/S能够高效催化环氧化物温和条件下被胺或醇开环生成对应β-氨基醇或β-烷氧基醇,并且催化剂能循环利用.ZrTf/S相较于AlTf/S和TiTf/S酸性最强,因而催化活性也最高.

关 键 词:环氧开环  酸催化  三氟金属  接枝催化剂  介孔硅

Abstract:Metal (Al,Ti,Zr) triflate grafted mesoporous SBA-15 (AlTf/S,TiTf/S,ZrTf/S) samples were synthesized as inexpensive solid acid materials by a simple one-pot-two-step synthesis methodology.These materials were characterized by X-ray diffraction,N2-sorption,thermogravimetric analysis,Fourier transform infrared spectroscopy (FT-IR),in-situ pyridine FT-IR spectroscopy,and elemental analysis.ZrTf/S was found to be a highly efficient and reusable solid acid catalyst for ring opening of epoxides with amines and alcohols and produced β-amino alcohols and β-alkoxy alcohols respectively under ambient reaction conditions.The ZrTf/S catalyst showed the highest activity,which was attributed to its high acidity compared with that of the Ti and Al containing samples.
Keywords:Epoxide ring opening  Acid catalysis  Metal triflate  Grafted catalyst  Mesoporous silica
