We found that the ECH reactions to FA and MF were both dependent on the concentration of furfural until concentrations of 60mM at which a plateau was seen, following a Langmuirian trend. Homogeneous side reactions occurred in solutions of pH 0 and 1 in which both FA and MF were lost. The homogeneous side reactions were concentration dependent in FA and MF and impacted the performance of ECH. By deriving kinetic relations for the desired and non-desired reactions, we showed that the as the conversion continued to increase, the yield in a batch reactor reached a peak before dropping (Figure 1). The kinetic relations from this work can assist in modeling of reactors to check for the impact of acidic conditions and impact onto the desired yield.
