the first time, the alkylation of 2-methylfuran with mesityl oxide was carried out over a series of solid acid catalysts. Among the investigated candidates, Nafion-212 resin exhibited the highest catalytic efficiency and good stability, which can be rationalized by the higher acid strength of this catalyst. The hydrodeoxygenation (HDO) of the alkylation products of 2-methylfuran with mesityl oxide was
首次在一系列固体酸催化剂上进行了2-甲基呋喃与异亚丙基丙酮的烷基化反应。在所研究的候选物中,Nafion-212树脂表现出最高的催化效率和良好的稳定性,这可以通过该催化剂的更高酸强度来合理化。还研究了2-甲基呋喃与异亚丙基丙酮的烷基化产物的加氢脱氧(HDO)。Ni–Mo 2 C / SiO 2和Ni–W 2 C / SiO 2首次用于生物质衍生含氧化合物的HDO,并显示出优异的催化性能,可将烷基化产物转化为烷烃。与Ni–W 2 C / SiO 2相比,Ni–Mo 2 C / SiO2对柴油系列烷烃显示出更高的选择性。在Ni-Mo 2 C / SiO 2催化剂上,通过在573 K和6.0 MPa H 2下2-甲基呋喃和异亚丙基丙酮的烷基化产物的HDO,可以实现柴油范围烷烃的高碳收率(77%)。该值明显高于在相同反应条件下通过贵金属催化剂和Ni–W x C / AC获得的值。
