Indian Natural Zeolites Catalyzed Urea Furfural Green Polymerization

Kiran M. Khandarkar, Mudrika Ahmed, Jyotsna S. Meshram

Zeolites have been used as an efficient and cost effective activating catalyst for the synthesis of furfural urea resin. The condensation of furfural with urea is conducted in aqueous and organic phase with natural as well as synthetic zeolite as catalyst. The catalysts are recycled and reused several times. This reaction is scalable to milligram scale and the methodology has resulted in an efficient synthesis with superior product. Herein benign, environ friendly, efficient and extremely fast procedure for the synthesis of untainted, superior furfural urea resin (FUR) have been demonstrated. The white FUR is characterized by 1H and 13C NMR, FTIR, X-ray diffraction and thermal analysis (DTA, TG, DSC).
