本研究以甲基苯甲醛和丙酮这两种可从木质纤维素中获得的平台化合物为原料，制备了航空燃料级高密度双环烷烃。质子化钛酸盐纳米管（PTNTs）是一种廉价且易于制备的固体酸催化剂，首次被发现是一种稳定、耐用和高效的催化剂，用于丙酮和甲基苯甲醛的酸催化醛缩反应制备喷气燃料前驱体。在这种催化剂上，在温和的反应条件下，喷气燃料前驱体的产率达到了很高（~ 76%）。PTNT催化剂可重复使用而无明显失活，在实际应用中具有优势。在表征的基础上，PTNT催化剂的良好性能可归因于其特殊的纳米管形态、更大的表面积、更高的酸位量和酸强度。喷气燃料前驱体在环己烷中加氢脱氧后，在温和条件下（403 K, 5 MPa, 2 h），获得了高收率（约90%）的双环烷烃。这些双环烷烃的密度比普通的喷气燃料要高。因此，它们可能被混合到喷气燃料中，以提高飞机的航程（或有效载荷）。
In this work, jet fuel range high-density dicycloalkanes were manufactured from methyl benzaldehyde and acetone, two platform compounds which may be obtained from lignocellulose. Protonated titanate nanotubes (PTNTs), a cheap and easily prepared solid acid catalyst, was first found to be a stable, durable and highly efficient catalyst for the preparation of the jet fuel precursors by the acid-catalyzed aldol condensation of acetone and methyl benzaldehydes. Over this catalyst, high yield (∼76%) of jet fuel precursors was reached under mild reaction conditions. The PTNT catalyst can be repeatedly used without significant deactivation, which is advantageous in real application. On the basis of the characterization, the good performance of the PTNT catalyst can be attributed to its special nanotube morphology, bigger surface area, higher acid site amount and acid strength. After the hydrodeoxygenation of jet fuel precursors in cyclohexane under mild conditions (403 K, 5 MPa, 2 h), high yields (∼90%) of dicycloalkanes were achieved. These dicycloalkanes have higher densities than ordinary jet fuel. Therefore, they may be blended into jet fuel to raise the range (or payload) of airplanes.
