Conclusions
-
1.
Primary alcohols are dehydrogenated on samarium oxide to a greater degree than they are dehydrated, and the dehydrogenating ability increases as the molecular weight of the primary alcohols is increased. Secondary isopropanol is dehydrated to a greater degree.
-
2.
On samarium oxide, alkyl substituants on the α- and β-carbon atoms, when two hydrogen atoms are replaced by methyl, exert a great influence on the value of the activation energy of dehydrogenation.
-
3.
The bond energies of C, H, and O with Sm2O3 were determined by a kinetic method.
