✔ 最佳答案
2,5-furandicarboxylic acid (FDCA), having similar chemical structure with terephthalic acid (PTA), is suitable for being used as the raw material for synthetic polyester. FDCA can be produced by acid-catalyzed dehydration of fructose, a source-abundant bio-material, followed by catalytic oxidation. This research, cooperating with the Development Program on FDCA Production of the ITRI, MCL, aims at the investigation of purification methods for FDCA. Consideringthe physical and chemical characteristics of FDCA and planning a number of purification procedures with experimental studies, it was concluded that the best purification method is to purify FDCA by cooling and crystallization,using ethylene glycol as solvent.
