摘要: 乙醇酸是一种结构最为简单的α-羟基羧酸,广泛用于材料、医学和环保等领域。然而当前乙醇酸合成技术存在工艺复杂和产品脱杂质成本高等问题。在“双碳”背景下,开发全新生物质基乙醇酸合成技术具有重要意义。生物质基乙醇酸合成的研究于30年前开始兴起,在近5年成为研究热点。从合成方法和技术路线两个方面,详细比较了纤维素直接转化法、糖类液相氧化法等不同合成方法的特点。指出未来的研究重点在于积极探索新型催化剂设计方法和生物质基乙醇酸合成新工艺。

Abstract: Glycolic acid is a kind of α-hydroxy-carboxylic acid with the simplest structure, which is widely used in materials, medical treatment and environmental protection and so on. However, the current glycolic acid synthesis technology has some problems, such as complex process and high cost of impurity removal. Under the background of ‘double carbon’, it is of great significance to develop a new synthesis technology of bio-based glycolic acid. The research of biomass-derived glycolic acid synthesis began to rise 30 years ago, and became a research hotspot in the past 5 years. The characteristics of different synthesis methods, such as cellulose conversion method and saccharide liquid phase oxidation method, were compared in detail from two aspects of synthetic methods and technical routes. It is pointed out that emphasis in the future lies in the active to exploration of new catalyst design method and new process for synthesis of bio-based glycolic acid.
