Conversion Of Glucose Into 5-hydroxymethylfurfural Using Zeolitic Catalysts In Wateracetone As Solvent

Production of 5-hydroxymethylfurfural, which is an important bio-resource intermediate,rnfrom glucose was examined in water/acetone solvent system, synthetic and modifiedrnmordenites and SAPO-5 materials as catalysts. The treatment of glucose at 100 oC withrnmordenite and at 120 oC with SAPO-5 materials gives limited amount of conversion.rnModified mordenite at100 oC and 48h gave 28.41% and the SAPO-5 materials: 1.5T,rnwhich have a number of Bronsted acid sites but weaker in strength gave 13.66% ofrnconversion while that of 1.5B which has a stronger Bronsted acidities gave 18% at 120 oCrnand 24 h in monophasic systems. In the case of biphasic system, a yield of 7.38 % at 6 hrnwas obtained using synthetic Mordenite at 150 oC. Despite the efforts, the system is notrnyet optimized.
