Catalytic Reactions and Analysis of Products
General procedure: The detailed reaction conditions are described in the figure captions and table footnotes.The one-pot conversion of lignin was conducted in a 25 mL stainless-steel autoclave reactor. In a typical reaction, lignin (0.10 g), catalyst (0.20 g), and dodecane(5 mL) were filled into the reactor, which was then sealed, purged three timeswith H2, and charged to an initial pressure of 0.5 MPa with H2. The reactor was heatedto a target temperature, and the reaction conducted with magnetic stirring. Afterthe reaction, the reactor was quenched in an ice-water bath, and the reactionmixturewas centrifuged to separate the catalyst. The organic phase was qualitativelyanalyzed by gas chromatography-mass spectrometry (GC-MS) (Agilent 7890A-5975C) and quantitatively analyzed by a GC-flame ionization detector (Agilent7890A) with an HP-5 column. The column temperature began at 50C (held for5 min) andwas then raised at 10Cmin1 to 250C (held for 1 min); the total runningtime was 26min. Pentadecane was used as an internal standard for the quantificationof the liquid products. For the stability test, after each reaction, the used catalyst wasisolated by centrifugation, washed with ethanol to remove the unreacted lignin, anddried at 80C in air overnight before the next run. The theoretical yield of ligninmonocyclic units was determined by the established NBO method (NoteS1).23,37,38 The conversion of lignin models and product analysis were conducted with the same method.
