Summary: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.
