Fe-Mg-O/γ-Al_2O_3对苯酚羟基化制苯二酚催化作用的研究

Studies on Fe-Mg-O/γ-Al_2O_3 catalyzing phenol hydroxylation for preparing diphenols

采用自行合成的Fe Mg O/γ Al2 O3 催化剂 ,对苯酚羟基化反应进行了研究 ,重点考察了催化剂用量、溶剂用量、反应温度、反应时间、诱导期对反应结果的影响 。

This paper mainly deals with Fe-Mg-O/γ-Al 2O 3 used in the phenol hydroxylation under mild conditions. The key study is focused on these factors including the usage of catalyst and solvent,reaction temperature and reaction time, revulsive time etc. Finally, the shortage and advantage of magnesium ferrite catalyst are discussed.
