Embodiment 1
[0099] Example 1: Glucose to Glucaric Acid
[0100] Several catalysts were obtained from commercial vendors: Johnson Matthey 5% Pt / C (three examples; JM-23 [B103032-5, Lot #C-9090]; JM-25 [B103014-5, Lot #C9230]; and JM-27 [ B-501032-5, Lot #C-9188]), Johnson Matthey 5% Pt / Al 2 o 3 (two examples; JM-32 [B301013-5, Lot #C8959] and JM-33 [B301099-5, Lot #C9218]), and BASFEscat23515% Pt / SiO 2 [Lot#A4048107]; and 1.5% Au / TiO 2 [Süd Chemie 02-10]. Other catalysts were prepared according to the procedures described herein.
[0101] Preparation of Supported Platinum Catalyst
[0102] Properly concentrated Pt(NO 3 ) 2 Portions of aqueous solution (Heraeus) were added to a suitable carrier (where Pt(NO 3 ) 2 The total combined volume of the solution was matched to be equal to the pore volume of the chosen support) and stirred between additions. After impregnation, the product was dried in an oven at 120°C for 12 hours. by flowing at 200°C or 350°C in N 2 5vol.%H 2 The mate...
Embodiment 2
[0117] Example 2: Glucaric acid to adipic acid
[0118] Preparation of M1 / carrier catalyst (M1=Ru, Rh, Pd, Pt)x
[0119]2 g of dry 5 μm silica Cariact (FujiSilysia) or 45 μm titanium dioxide NorPro ST61120 (Saint-Gobain) were weighed into vials. Suitably concentrated M1 stock solutions (M1 = Ru, Rh, Pd, Pt) were prepared from concentrated acidic stock solutions purchased from Heraeus (see Table 1). For each M1, multiple addition portions of the diluted M1 stock solution were added to the support (silica pore volume = 0.7 mL / g, titanium dioxide NorPro = 0.45 mL / g) until 1.4 ml (silica) or Total volume of 0.9 mL (titanium dioxide). After each addition, the mixture was stirred to impregnate the support. After impregnation, the Xwt.% M1 / support mixture (X=2-5) was dried in an oven at 120°C for 12 hours.
[0120] Preparation of M1 / M2 / support catalyst (M2=Ru, Rh, Pd, Ir, Pt, Au, Mo)
[0121] 7-12 mg dry Xwt.% M1 / vehicle (M1 = Ru, Rh, Pd, Pt) (X = 2-5) was dispensed into an 8x12...
