Gold nanoparticle stabilization within tailored cubic mesoporous silica: Optimizing alcohol oxidation activity. Catalytic oxidation of 1,2-dichloroethane over Al Effect of crystalline phases and acid sites on the dehydration of 1-octadecanol to 1-octadecene over TiO2–ZrO2 mixed oxides. Maxime Caillot, Alexandra Chaumonnot, Mathieu Digne, Jeroen A. van Bokhoven. N2 - Steady-state rates of ether formation from alcohols (1-propanol, 2-propanol, and isobutanol) on γ-Al2O3 at 488 K increase at low alcohol pressure (0.1-4.2 kPa) but asymptotically converge to different values, inversely proportional to water pressure, at high alcohol pressure (4.2-7.2 kPa). Alkenes for IIT JEE. 2-Propanol has the highest rate constant for unimolecular dehydration among studied alcohols, demonstrating that stability of the carbocation-like transition state is the primary factor in determining rates of unimolecular dehydration which concomitantly results in high selectivity to the olefin. Save. 2 Production of linear α-olefin 1-octene via dehydration of 1-octanol over Al2O3 catalyst. 3 Deuterated alcohols show a primary kinetic isotope effect for unimolecular dehydration, implicating cleavage of a C-H bond (such as the Cβ-H bond) in the rate-determining step for olefin formation on γ-Al2O3. Van Bokhoven. Sai Sriharsha M. Konda, Stavros Caratzoulas, and Dionisios G. Vlachos . 1-Propanol and isobutanol have olefin formation rate constants higher than that of ethanol, indicating that olefin formation is also affected by carbon chain length.
