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.
