Abstract:

The thermal desorption of methanol and its decomposition products from magnesium oxide powder was recorded over the temperature range 300-1123 K. The formation of formaldehyde was observed in small quantities above 438 K. Large quantities of CO and H2 were evolved at 723-900 K, accompanied by smaller amounts of CH4. No ether formation was detected. Methanol desorption was observed below 773 K, with structure in the spectrum revealing at least two different phases of the desorption process. The variation of this structure with initial coverage serves to confirm and clarify previous models for methoxyl on MgO, based on infrared absorption studies. Author
