2，5-呋喃二甲酸（2，5-FDCA）是生物可降解聚呋喃二甲酸乙二醇酯（PEF）的单体，目前尚未形成廉价的制备技术，其中用己糖二酸脱水环合制备2，5-FDCA是一条具有发展潜力的路线。针对此路线中副产物定性不准确、反应路径研究不完善等问题，通过高效液相色谱、高分辨质谱、核磁共振和傅里叶变换红外光谱分析，开展了副产物定性工作，确定反应体系中的2个主要副产物为糠酸和3-羟基-6-羧基-2-吡喃酮（HOCA）。在硫酸催化下不同己糖二酸脱水环合的反应路径相似，半乳糖二酸易生成副产物HOCA，而葡萄糖二酸钙易生成主产物2，5-FDCA。结合文献报道，提出了己糖二酸脱水环合制备2，5-FDCA可能的完整反应路径。研究工作可为己糖二酸脱水环合制备2，5-FDCA的高效催化体系开发和工业化生产提供指导。
