Summary
-
1.
A study was made of the decomposition of isopropyl alcohol over ZnSe and ZnTe in the temperature range 20–140‡. Reaction proceeds mainly in the direction of dehydrogenation.
-
2.
There is a reduction of the catalytic activities of ZnSe and ZnTe during reaction. The activation energy for the dehydrogenation of the alcohol over ZnSe rises from 15 to 21 kcal/mole.
-
3.
The activity of ZnSe is reduced by roasting it in air at 600‡. Elementary tellurium has low catalytic activity.
-
4.
Investigation by x-ray- and electron-diffraction methods, taken in conjunction with the thermodynamic characteristics, showed that the phase changes in the catalyst were due to impurities in the original sample and to the effect of temperature, and not to the occurrence of the catalytic reaction.
