Description

General description

Methan(ol-d) (Methanol-OD, CH₃OD) is a deuterated form of methanol. Dissociation of CH₃OD adsorbed on the clean W(100) surface resulted in the formation of hydrogen, carbon and oxygen (β-CO). Additionally, carbon dioxide, water and methyl formate were obtained when similar dissociation was conducted over the W(100)-(5×1)C surface. The dissociation process was monitored by temperature-programmed reaction spectroscopy. Self-diffusion coefficient, shear viscosities and densities of liquid CH₃OD have been determined by NMR spin-echo technique.

Application

Methanol-OD may have been used as solvent during cis-to-trans thermal isomerization of 1,3-diphenyltriazene using laser-induced optoacoustic calorimetry technique.
