| 1 | Dehydration of fructose and glucose to 5-hydroxymethylfurfural over Al-KCC-1 silica显示文摘In this research, the influence of several factors such as reaction time, catalyst weight, temperature and different solvents on dehydration reaction of fructose and glucose to 5-hydroxymethylfurfural(HMF) was surveyed. Nanosphere Al-KCC-1 silica with fibrous morphology was manufactured and used as proficient and recyclable catalyst for this reaction. SEM, TEM, BET, XRD, EDX, elemental mapping, ICP and FT-IR spectroscopy methods were applied for characterization of the Al-KCC-1(molar ratio Si/Al = 5, 40) catalysts. 162 °C and 1 h are the best conditions for the fructose dehydration. Under this situation HMF yield and selectivity are 92.9% and 94.5% respectively and fructose conversion is 98.4%. Also 170 °C and 2 h are the best conditions for the glucose dehydration. In this situation HMF yield and selectivity are 39.0% and39.9% respectively and glucose conversion is 97.8%. | Fereshte Shahangi Alireza Najafi Chermahini Mohammad Saraji | 2018 | Journal of Energy Chemistry2018，27，3： | 2 |
