INTERMEDIATES AND MECHANISMS OF THE HETER OGENEOUS CATALYTIC REACTIONS - THE REACTIONS OF HYDROCARBONS, ALCOHOLS, ACIDS

Structure of the surface intermediates in the heterogeneous catalytic transformations of hydrocarbons, alcohols and acids, obtained basing o n the spectral (mainly IR-spectral) investigations is studied. The cat alytic roles of definite structures are arranged in accordance with th e degree of trustworthiness: the lower degree - on the base of the spe ctra before and after catalysis, the middle degree - on the base of sp ectral data in situ, but without kinetic measurements, and the higher degree - on the base of spectral data in situ together with the compar ison of the reaction kinetics and the kinetics of the surface compound s concentration changes. Schemes of the heterogeneous catalytic reacti ons mechanisms are given, proposed on the base of the information abou t surface complexes.
