摘要/Abstract

摘要： 采用2-苯基-2氢-1,2,3-三唑-4-醛固载改性的MCM-41与醋酸钴共同催化的Henry反应。通过傅里叶变换红外光谱(FT-IR)和X射线多晶衍射(XRD)等技术手段对催化剂进行了表征。在室温下考察了金属盐、溶剂对反应的影响，催化剂循环使用3次后催化活性基本无变化(产率可达80.5%)。

Abstract: The catalytic properties of 2-phenyl-2H-1,2,3-triazole-4-carbaldehyde functionalized mesoporous molecular sieve MCM-41 materials and cobalt acetate in the nitroaldol(Henry) reaction are reported. The catalyst was characterized by methods of Fourier transform infrared spectroscopy(FT-IR) and X-ray diffraction(XRD). The reaction conditions such as metal salts, different solvents were investigated at room temperature. And the catalyst can be separated by simple filtration and reused for several times without much loss in performance with the yield up to 80.5%.

Key words: Schiff base, MCM-41, catalysis, Henry reaction
