聚乙醇酸的合成及工业化进展

Synthesis and Industrialization Progress of Polyglycolic Acid

聚乙醇酸(PGA)作为一种可完全生物降解材料,受到国内外研究者的广泛关注。概述了近年来PGA的主要合成路线及催化剂体系。伴随煤制乙二醇技术的发展,着重介绍了煤制合成气路线制备PGA及PGA工业化进展,展望了我国自主研发的合成气制PGA路线的前景。

As a completely biodegradable material,polyglycolic acid(PGA)has been widely concerned at home and abroad.The main synthetic routes and catalyst systems of PGA in recent are reviewed.With the development of coal-to-glycol technology,PGA preparation by coal-to-gas route and industrialization progess of PGA are emphatically introduced.The prospect of China′s self-developed synthetic gas to PGA route is prospected.
