| Popis: | Simultaneous adsorption of diolefine, hydrogen, and hydrogen sulfide on platinum single crystals induces mercaptan and alkane formation. The nature, the amount and the temperature of desorption of these products depend on the size and configuration of the diolefine and on the structure of the surface. Mechanisms have been proposed to interpret the observed surface reactions. A selective number of compounds are selectively produced when H2S reacts firstly with the diolefine; this occurs with C4H6 on both (111) and (110) orientations and with C5H8 on Pt(110). But hydrogen is the first to react with C5H8 on Pt(111), leading thus to a whole series of mercaptans and saturated hydrocarbons. |
