WebMay 19, 2024 · Additional insight into the mechanism of reaction is obtained through the use of deuterated toluene (C 6 D 5 –CH 3 and C 6 H 5 –CD 3) on O/Au (Fig. 2).In the case of C 6 D 5 –CH 3, the evolution of products takes place at the same temperature than for non-deuterated toluene (300 K).A kinetic isotope effect (KIE) would be expected if … Webin deuterated toluene at several temperatures [51]. Rg de-creased from 116 Å at 25 Cto55Åat100 Candwas explained by aggregate dissociation rather than an asphal-tene conformational change. Aggregate size changes caused by temperature variation were, however, reversible. Espinat et al. measured the scattered intensity from asphaltenes in
