The study by Ayestarán Latorre et. al. investigated the mechanochemical decomposition of trialkyl phosphates between 300-500 K and 1-4 GPa for α-Fe(110) surfaces. Comparing the current results to this previous study, it is clear that triaryl phosphates such as TCP had much lower decomposition rates than trialkyl phosphates under the same conditions. This observation agrees with previous experimental and simulation studies of the thermal decomposition of phosphate esters on ferrous surfaces.
