^aThe amount of Mo was arround 0.025 mmol (1 wt% to Ru metal based on the amount of precursor). Reaction conditions: catalyst, 0.065 g; lauric acid, 3.2 mmol; solvent, 2-propanol: H₂O, 5 ml (4.0 : 1.0 volume ratio), 170 °C; H₂ 40 bar, 7 h.

^bConversion and yield were determined by GC using an internal standard technique.

^cOthers include dodecyl dodecanoate as the esterification of lauric acid and dodecane-1-ol and products with smaller carbon number according to GC-MS profiles.

^dThe catalysts were prepared using physical mixing at room temperature, dried at 110 °C for 5 h, followed by reduction with H₂ at 500 °C for 3 h.

^eThe catalyst was prepared using one-pot hydrothermal of RuCl₃ and (NH₄)₆Mo₇O₂₄·4H₂O mixture solutions at 150 °C for 24 h, followed by reduction with H₂ at 500 °C for 3 h. The carbon balance was 93–96% for all the catalyst.
