This paper presents the successful use of ruthenium nanoparticles, stabilized in water by ammonium surfactants, in the selective hydrogenation of α-pinene and the first industrially reported scale-up of this catalyst on a multigram-scale. After designing the nanocatalyst at the lab scale, operational parameters (substrate/metal ratio, pressure, and temperature) were identified and optimized in the scale-up. The α-pinene hydrogenation process was operated with a 200 g batch, under 30 bar H₂ and at 110 °C, with a complete conversion and a selectivity of 98% into cis-pinane within 4 h. The catalyst was easily recycled through a liquid–liquid biphasic approach for 5 reaction cycles to achieve a total turnover number (TTON) of 14000.

水中纳米钌与α-P烯选择性加氢的克数放大

本文介绍了通过铵表面活性剂稳定在水中的钌纳米粒子在α-pine烯的选择性加氢中的成功应用以及该催化剂在工业上首次报道的以克为单位的规模放大。在实验室规模设计纳米催化剂后，确定了运行参数（基材/金属比，压力和温度）并在放大时进行了优化。α-pine烯加氢过程以200 g的批料在30 bar H _2下和110°C下进行，在4 h内完全转化，选择性为98％生成顺式pin烷。该催化剂可通过液-液双相法轻松地循环使用5个反应周期，从而使总周转数（TTON）为14000。
