For a typical hydrogenation experiment, in a glove box, biomass (91 mg) and Ru-MACHO-BH (1.8 wt%, 1.6 mg) were weighed in a glass vial equipped with a magnetic stir bar and sealed with a Teflon-lined cap. Upon bringing the glass vial outside the glove box, 1 mL of solvent (H2O) followed by addition of 85 w/w% aqueous phosphoric acid. Subsequently, the vial was placed in a seven-well reactor with a needle placed through the rubber stopper of the vials for the gas flow. The high-pressure reactor was sealed tightly and flushed with argon/hydrogen (three times) and finally required hydrogen pressure (30 bar) was loaded into the high-pressure reactor and desired temperature of 140 °C was also applied. The reactor was cooled to room temperature before the hydrogen was released and the sample was prepared for GC analysis with 1,4-dioxane as the internal standard.
