Inhibitor mixtures used for suppression of polyoxymethylene oxidation

Investigation of the Oxidative Degradation of the Synthetic Fuel Oxymethylene Dimethyl Ether

“…This degradation can be inhibited with AOs like BHT. BHT is a sterically hindered phenol and a commonly used AO in the fuel sector. , Sterically hindered phenols are also known to inhibit the degradation of POM , and were therefore chosen as the AO for this study.…”

“…In these works it was established that POM degrades through chain reactions of free radicals at temperatures between 100 and 170 °C. These chain reactions can be slowed down with antioxidants (AO) as demonstrated by Gur’yanova et al and Nikitina et al Light is known to accelerate the degradation by starting the chain of the degradation process . More recent studies focus on the kinetic modeling of POM degradation and the analysis of its degradation products. , In a recent work, the stability of OME was found to be worse compared to diesel fuel under the accelerated degradation conditions reported by Schröder and Görsch but better compared to diesel fuel at moderate temperatures.…”
