The self-etherification of 5-hydroxymethylfurfural (HMF) to 5,5′(oxy-bis(methylene))bis-2-furfural (OBMF) was investigated on ZSM-5, MCM-22, beta and hierarchical micro–mesoporous ZSM-5 (HMZ) catalysts. The hierarchically structured zeolites exhibited a superior intrinsic activity and good resistance to carbonaceous deposit; the latter could be ascribed to the lower mass transfer barrier in the mesopores of the HMZ catalysts. The structure–activity correlation showed that the catalytic activity mainly originated from one or several specific Brønsted acid sites, providing key clues to design efficient zeolite catalysts for producing OBMF.

沸石催化剂上5-羟甲基糠醛催化自醚化为5,5'（氧-双（亚甲基））双-2-糠醛：孔结构和酸度的影响

在ZSM-5，MCM-22，β和分级微介孔ZSM上研究了5-羟甲基糠醛（HMF）到5,5'（氧基-双（亚甲基））双-2-糠醛（OBMF）的自醚化-5（HMZ）催化剂。分层结构的沸石表现出优异的内在活性和对碳质沉积物的良好抵抗力。后者可归因于HMZ催化剂中孔中较低的传质屏障。结构活性相关性表明，催化活性主要来源于一个或几个特定的布朗斯台德酸位，这为设计生产OBMF的高效沸石催化剂提供了重要线索。
