Abstract

A (super)critical transfer: The consecutive hydrogenolysis and hydrogenation of the lignin model compound dihydrobenzofuran was studied in supercritical methanolic solutions using porous metal oxide catalysts. These catalysts promote H(2) production from methanol followed by hydrogenolysis of the ether linkages and reduction of the aromatic rings, leading principally to a mixture of cyclohexanols.

摘要

一种(超)临界转移:使用多孔金属氧化物催化剂,在超临界甲醇溶液中研究了木质素模型化合物二氢苯并呋喃的连续氢解和氢化反应。这些催化剂促进甲醇产生氢气,随后使醚键氢解并使芳环还原,主要生成环己醇的混合物。
