Table 4. Hydrogenolysis scale-up of consumer polymer products using [Ru(triphos)tmm] (A)/[Ru(triphos-xyl)tmm] (B) and HNTf2.*.
| Entry | Conversion (%)† | Selectivity (%)† | Polymer source (g) | Catalyst (mol %) |
| 1 | >99 | >99 | Drinking cup, PLA (11.4) | A 0.05 |
| 2‡ | >99 | 98 | 0.5-Liter water bottle, PET (13.2) + screw cap, PP and labeling, PE (2.9) | B 0.2 |
| 3‡ | >99 | >99 | 0.5-Liter water bottle, PET (13.2) | B 0.1 |
| 4 | >99 | >99 | CD, PC (16.1) | A 0.5 |
*Reaction conditions: The reactions were performed in a 500-ml steel autoclave using 16-hour reaction time, x mol % [Ru(triphos)tmm] (A) and HNTf2, 140°C, 120 ml of 1,4-dioxane, and 90-bar constant hydrogen pressure.
†Conversion and selectivity were determined by 1H NMR spectroscopy using mesitylene as internal standard.
‡[Ru(triphos-xyl)tmm] (B) and HNTf2 were used.
