Background reduction of styrene to ethylbenzene caused by catalyst contamination on the SAH3 system.a
| Entry | Details | [Styrene] | Conversionb |
| 1 | Prior to system wash | 0.5 M | 22.5, 23.6% |
| 2 | After system wash with AcOH, DMF, MeOH | 0.5 M | 14.6, 14.0, 16.4% |
| 3 | After system wash, disassembly and cleaning, test run 1 | 0.5 M | 2.2, 3.0, 3.2% |
| 4 | After system wash, disassembly and cleaning, test run 2 | 0.05 M | 6.1, 11.5% |
aAll reactions were performed in MeOH using a 30 mm quartz CatCart® at a flow rate of 1.0 mL/min, full H2 mode, 30 °C, 2 mL injection per reaction, 10 mL volume collected. bConversion determined by GC–MS analysis with decane as an internal standard. Individual results from multiple experiments are shown.
