For the first time, we demonstrated two integrated processes for the direct synthesis of dodecanol or 2,4,8‐trimethylnonane (a jet fuel range C12‐branched alkane) using methyl isobutyl ketone (MIBK) that can be derived from lignocellulose. The reactions were carried out in dual‐bed continuous flow reactors. In the first bed, MIBK was selectively converted to a mixture of C12 alcohol and ketone. Over
首次,我们展示了使用可以衍生自木质纤维素的甲基异丁基酮(MIBK)直接合成十二烷醇或2,4,8-三甲基壬烷(喷气燃料C 12支链烷烃)的两种集成工艺。反应在双床连续流反应器中进行。在第一床中,将MIBK选择性转化为C 12醇和酮的混合物。在Pd改性的镁铝水滑石(Pd-MgAl-HT)催化剂上,在温和的条件下可以实现较高的C 12含氧化合物总碳收率(73.0%)。在第二张床上,C 12在第一个床中生成的含氧化合物在Ru / C催化剂上氢化为十二烷醇,或在Cu / SiO 2催化剂上加氢脱氧为2,4,8-三甲基壬烷。如此获得的十二烷醇可用作十二烷基硫酸钠(SDS)和十二烷基苯磺酸钠(SDBS)的生产原料,它们被广泛用作表面活性剂或清洁剂。所获得的2,4,8-三甲基壬烷无需加氢异构化即可掺入常规喷气燃料中。
