In this work the one-pot production of pentyl valerate (PV) from γ-valerolactone (GVL) and pentanol in liquid phase at 523 K, 10 bar of H₂ over Ni-based catalysts supported on SiO₂-Al₂O₃ (SA) was studied. By using incipient wetness impregnation (I) and precipitation-deposition (PD) two different catalysts were prepared, characterized and tested in reaction. With larger Ni⁰ particles and a significantly higher acid site density, Ni/SA-I was more active and selective to PV, revealing the crucial impact of preparation method on the catalytic performance. After 24 h, a GVL conversion of 83.5% with PV selectivity of 87.8% was reached with Ni/SA-I.

在这项工作中，在SiO ₂ -Al ₂ O ₃上负载的Ni基催化剂上，在523 K，10 bar H _{2的条件下}，从γ-戊内酯（GVL）和戊醇在液相中一锅法生产戊酸戊酯（PV）（ SA）进行了研究。通过使用初期湿润浸渍（I）和沉淀沉积（PD），制备了两种不同的催化剂，进行了表征和反应测试。Ni / SA-I具有较大的Ni ⁰颗粒和明显更高的酸位密度，对PV更具活性和选择性，从而揭示了制备方法对催化性能的关键影响。24小时后，Ni / SA-I达到了83.5％的GVL转化率和88.7％的PV选择性。
