(a) Used model reaction. (b) Decrease of 2-ethylhexyl amine as a function of time at 100 °C in the presence of different additives, which reaches equilibrium for a fraction of remaining 2-EHA of ∼0.17. The amount of catalyst was calculated as mol% versus 2-ethyl hexyl amine (Table 2). (c) Arrhenius plot of an extended kinetic study (Supplementary Fig. 2).
