Abstract

This study investigates the optimization and improvement of the polyglycolic acid synthesis process from three perspectives: process parameters, catalysts, and raw material pretreatment. Parameters such as reaction temperature, time, pressure, and monomer concentration were optimized, and their effects on the reaction and product were analyzed. The performance and improvement methods of metal compounds, organic, supported, and composite catalysts were explored. Furthermore, optimization efforts were made to increase raw material purity, control water content, remove impurities, and improve pretreatment conditions. This study provides a comprehensive and detailed technical reference for the efficient synthesis of polyglycolic acid.
