- W2065571755 abstract "A study has been made of the reactions of normal 1-alcohols (ethanol, propanol, hexanol, octanol, dodecanol and octadecanol) and of hydrocarbons (n-heptadecene-1 and n-octacosane) on a sample of natural montmorillonite, under conditions whereby the products were rapidly removed from the active surface through condensation at −196 °C. These reactions yielded equilibrium mixtures of isomeric straight-chain olefins. Reactants having chain length >C8 underwent significant cracking to yield products in C4C8 (at least) hydrocarbon boiling range; the composition of the product mixtures were closely similar, although the absolute yields varied with the different reactants. A reaction mechanism involving initial adsorption at Lewis acid sites is proposed to account for the surface reactions, which involve double bond migration and cracking of the hydrocarbon chain. The reactions of the same alcohols, under conditions in which products and water vapour readsorption was possible, yielded mixtures consisting predominantly of branched alkanes; the production of olefins was small. There was evidence that surface reactions involved polymerization, cracking, skeletal isomerization and hydrogenation processes. All reactants gave similar product distributions and the amounts formed increased with chain length of the reactant as far as dodecanol. A reaction mechanism involving carbonium ion formation at Brönsted acid sites is proposed to account for these observations. It was concluded that the mineral enabled facile movement of hydrogen and the availability of this element was greatest where reaction conditions did not favour surface dehydration. The present results are considered to provide information concerning: (i) the properties of acid groups which occur in silica-alumina catalysts, and (ii) (not discussed in the present article) the possible participation of reactions at clay mineral surfaces in petroleum genesis." @default.
