DFRC法在木素结构研究中的应用

Application of DFRC in the Study of Lignin Structure

作为木素分析的新方法,DFRC法可以有选择性的高效的断裂β醚键和α芳基醚键,而甲氧基没有发生任何变化,并且反应条件温和,缩合反应很少,这都为进一步的结构分析提供了保证。本文综述了DFRC法的原理、反应条件及国内外的应用现状,分析了存在问题及难点,探索了今后的应用方向。

A new method for selective and efficient cleavage of arylglycerol-β-ether （β-O-4） linkage and α-aryl ether bonds, DFRC method, is introduced in this paper. The DFRC method produces simpler mixtures of monomers with high yields than alternative hydrolytic methods. Because of its relative simplicity, mild conditions and exceptional selectivity, this method should become a powerful analytical method for lignin characterization. This article reviews current research development of this method. In addition, the problems and difficulties involved are also discussed.
