在制浆及漂白时纸浆中的一些阴离子物质会发生降解释放到浆水体系中,糖醛酸是这些阴离子物质的主要来源之一。研究糖醛酸的来源、含量及其结构变化可为解决工业生产中的问题提供理论依据。目前化学、生物学、药物学等领域对糖醛酸的研究已经越来越深入。本文论述总结浆水体系中糖醛酸的分离纯化、结构鉴定的可行方法和研究现状。 During pulping and bleaching, some of the anionic material in the pulp is degraded and released into the syrup system. Uronic acid is one of the major sources of these anionic materials. Studying the origin, content and structural changes of uronic acid can provide a theoretical basis for solving the problems in industrial production. At present, the research on uronic acid in chemistry, biology, pharmacy and other fields has been more and more in-depth. This article discusses the summary of syrup in syrup separation and purification, structural identification of viable methods and research status.
