Steps:

2.3 Hydrogenation of benzaldehyde
Liquid-phase hydrogenation of BzH was conducted in a 10-mL Teflon-lined stainless steel autoclave reactor. In a typical hydrogenation reaction, 20 mg of the Pt/MgAl₂O₄ catalyst (or 1μmol equivalent of Pt) was suspended in 5 mL ethanol containing 100 μL BzH (>97%, AIKE Reagent, ～1 mmol). After the air was replaced three times with H₂, the autoclave was charged with H₂ (1.0 MPa) and maintained at various temperatures for various time under vigorous magnetic stirring. The absence of external diffusion limitations was verified by performing the reaction under various stirring rates in preliminary experiments. After the reaction, the autoclave was quenched with cold water. A reusability test was conducted with the 0.2Pt/MgAl₂O₄ catalyst, whereby the used catalyst was collected and recovered by filtration and washing with ethanol. The shortfall in the recovered catalyst was replenished with catalysts from other reactors that had undergone the same number of runs. The products were analyzed by gas chromatography (7890B, Agilent Technologies) using an HP-INNOWAX capillary column (30 m × 0.32 mm, Agilent Technologies) and a flame ionization detector.
