Abstract

Novel hierarchical niobium-containing zeolites were synthesized for the first time and applied for isomerization of dihydroxyactetone to alkyl lactate and lactic acid (95-97% yield). These materials possess secondary mesoporosity, thus facilitating access to active sites of the material by larger reagent molecules, preserving acidity and crystallinity of the zeolites.

摘要

首次合成了新型含铌的沸石，并将其应用于二羟丙酮异构化为乳酸乙酯和乳酸（产率 95-97%）。这些材料具有二级介孔结构，因此可以使较大的反应分子更容易进入材料的活性位，同时保持沸石的酸性和结晶度。
