実験手順
Wet Raney Ni 4200 (˜70 mg, 1×10−3 mol, 500 mol %), KOH (37 mg, 7×10−4 mol, 300%) and Lignin type B (40 mg, 2.2×10−4 mol, dry), is weighed into a reaction flask under argon. Degassed Dioxane (3 mL) and i-PrOH (1 mL) is added and the flask is capped with a rubber septa and the mixture is heated (120° C.). The reaction is run for 18 hours and the reaction mixture is cooled. MeOH is added and Nickel was removed with a magnet, and the mixture is neutralized. The reaction mixture is injected into an HPLC-system (GPC).
