The amount of Mo was arround 0.025 mmol (based on the 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.
Conversion and yield were determined by GC using an internal standard technique.
Dodecyl dodecanoate is included as the esterification of lauric acid and dodecane-1-ol. The carbon balance was 93–96% for all the catalysts.
At 230 °C, 40 bar, 7 h.
At 180 °C, 80 bar, 4 h.
At 160 °C, 30 bar 20 h.
