Figure 5. Pressure effect on the formic acid yield using [RuCl2(PTA)4] catalyst in DMSO.

Figure 5

Reaction conditions: [RuCl2(PTA)4] (2.76 mM), t=50 °C, P(H2)/P(CO2) ratio of 1, reaction time 120 h, DMSO (2 ml), average values of several (two to six) measurements. The trend line is shown as a guide and is not a mathematical fit of the data.
