Biofuels synthesized from lignocellulose-derived platform chemicals are very attractive for sustainable development. Here we reported a new and facile route to synthesize multi-substituted cycloalkanes with a high density and low freezing point using isophorone and furanic aldehydes (furfural and 5-hydroxymethylfurfural), by solvent-free aldol condensation, followed by hydrodeoxygenation. Catalysts were screened and NaOH showed good performance. The reaction conditions including catalyst dosage, isophorone/furanic aldehyde ratio, temperature and solvent were optimized, and finally the yields of 70.0% for isophorone/furfural and 72.8% for isophorone/5-hydroxymethylfurfural were obtained. Pt/HZSM-5 was prepared as the bifunctional catalyst for hydrodeoxygenation of the condensed product. The resultant multi-substituted cyclohexanes derived from isophorone/furfural and isophorone/5-hydroxymethylfurfural have a density of 0.813 g mL⁻¹ and 0.846 g mL⁻¹ respectively and both have a freezing point lower than −75 °C, and are very promising as stand-alone fuels or additives of other biofuels.

使用木质纤维素衍生的异佛尔酮和呋喃醛合成高密度和低凝固点的喷气燃料†

由木质纤维素衍生的平台化学品合成的生物燃料对于可持续发展非常有吸引力。在这里，我们报道了一种新的，简便的方法，可使用异佛尔酮和呋喃醛（糠醛和5-羟甲基糠醛），通过无溶剂的羟醛缩合，然后加氢脱氧，合成具有高密度和低凝固点的多取代环烷烃。筛选了催化剂，并且NaOH显示出良好的性能。优化了催化剂用量，异佛尔酮/呋喃醛比例，温度和溶剂的反应条件，最终得到异佛尔酮/糠醛的收率为70.0％，异佛尔酮/ 5-羟甲基糠醛的收率为72.8％。制备了Pt / HZSM-5，作为用于缩合产物加氢脱氧的双功能催化剂。^-1和0.846 g mL^-1的凝固点均低于-75°C，非常有希望作为独立的燃料或其他生物燃料的添加剂。
