Abstract: The decomposition of isopropyl alcohol on natural chalcopyrite CuFeS₂ was investigated in the temperature interval 474—673 К by the use of the microcatalytic pulse method. The dependence of conversion of isopropyl alcohol, selectivity of dehydrogenation, and selectivity of dehydration on temperature exhibits a discontinuity at 613 K. The authors deduce that the acceleration of dehydrogenation and inhibition of dehydration may be due to a change in catalytic properties of chalcopyrite caused by liberation of sulfur from its structure.
