This study discussed the catalytic cracking process of cellulose in ionic liquid 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([bmim]OTF) under 180°C, 240°C and 340°C, found that [bmim]OTF is an effective catalyst which can effectively reduce the pyrolysis temperature(nearly 200°C) of the cellulose. FRIR, XRD and SEM were used to analyze the structure characterization of fiber before and after
这项研究探讨了纤维素在离子液体1-丁基-3-甲基咪唑鎓三氟甲磺酸盐([bmim] OTF)中在180°C,240°C和340°C下的纤维素催化裂化过程,发现[bmim] OTF是一种有效的催化剂。可以有效降低纤维素的热解温度(近200℃)。FRIR,XRD和SEM分析了开裂前后纤维的结构特征。GC-MS用于液相产物分析;气相色谱用于分析气相产物。结果表明,[bmim] OTf中的纤维素热解主要生成CO2,CO和H2,还生成2-糠醇,2,5-二甲基-1,5-二烯丙基-3-醇,1,4-丁内酯,5 -甲基糠醛,4-羟基丁酸,丙酸乙烯酯,1-乙酰氧基-2-丁酮,呋喃甲酸四氢呋喃甲酯液体产品,
