The catalytic synthesis of liquid alkanes from renewable biomass has received tremendous attention in recent years. However, bio-based platform chemicals have not to date been exploited for the synthesis of highly branched lubricant alkanes, which are currently produced by hydrocracking and hydroisomerization of long-chain n-paraffins. A selective catalytic synthetic route has been developed for the production of highly branched C alkanes as lubricant base oil components from biomass-derived furfural and acetone through a sequential four-step process, including aldol condensation of furfural with acetone to produce a C double adduct, selective hydrogenation of the adduct to a C ketone, followed by a second condensation of the C ketone with furfural to generate a C aldol adduct, and finally hydrodeoxygenation to give highly branched C alkanes in 50.6 % overall yield from furfural. This work opens a general strategy for the synthesis of high-quality lubricant alkanes from renewable biomass.
近年来，从可再生生物质催化合成液态烷烃受到了极大关注。然而，迄今为止，生物基平台化学品尚未用于合成高度支化的润滑烷烃，目前这种烷烃是通过长链正构烷烃的加氢裂化和加氢异构化生产的。已经开发出一种选择性催化合成路线，通过一个连续的四步过程，从生物质衍生的糠醛和丙酮生产作为润滑基础油组分的高度支化的C烷烃，该过程包括糠醛与丙酮的羟醛缩合以产生C双加合物，将加合物选择性氢化为C酮，然后C酮与糠醛进行第二次缩合以生成C羟醛加合物，最后进行加氢脱氧，以50.6%的总收率从糠醛得到高度支化的C烷烃。这项工作为从可再生生物质合成高质量润滑烷烃开辟了一条通用策略。
