From: Partial oxidation of methane to methanol on boron nitride at near critical acetonitrile
The effect of methane to oxygen ratio on direct methane oxidation to methanol in near supercritical acetonitrile. All entries were conducted with 3 mL (57 mmol) of acetonitrile loaded into the reactor and cold fed (− 30 °C) with desired molar amounts of O2, CH4, and He. The reactor was heated with a ramp rate of ~ 2.5 °C/min up to 275 °C and the heater was programmed to switch off at 275 °C. A 60 rpm stirring speed was used. The samples were cooled to ambient temperature at the natural convection rate. Standard deviation (S. D.) was based on deviation in loading pressure. Methanol yield was calculated based on gas chromatography (GC) peak area calibration plots and reconfirmed with nuclear magnetic resonance (NMR) studies. The standard deviation of the yield was calculated by replicating one experiment and comparison with NMR data.
