The NMR microimaging is used for the first time as an in situ method to study two model three-phase heterogeneous catalytic reactions with strong exothermicity. It is shown for the α-methylstyrene hydrogenation that in the course of the reaction, two domains coexist inside the catalyst grain which differ in the liquid phase content. The 2D maps of the liquid distribution in the course of this reaction are obtained. The reaction of the hydrogen peroxide decomposition at moderate activity of the catalyst and the H2O2 concentrations in the range of (0.03-3) M is shown to occur only in a thin layer near the catalyst surface. The influence of the medium inhomogeneity on the behaviour of the Belousov - Zhabotinsky chemical oscillator reaction is investigated as well.
