Catalytic conversions of alcohols--7. Alkene selectivity of tungsten oxides
The reactions of C/sub 5/-C/sub 8/ alcohols, including 2- and 3-pentanol, trans-2-methylcyclohexanol, and 2-octanol, with and without alkene additions to the feed, were studied at 1 atm over hydrogen-treated and oxygen-treated tungsten oxides. The oxygen-treated catalysts yielded high cis-2/trans-2-alkene ratios from 2-alcohols; the hydrogen-pretreated catalysts yielded larger trans-2-alkene amounts from 2-alcohols. With oxygen-treated catalysts, the amount of trans-2-alkene increased slightly with increasing temperature, and the 1-alkene yield increased slightly with increasing chain length of the 2-alcohol. No cis-trans isomerization was observed with 2-methylcyclohexanol. Surface reactions and intermediates are briefly discussed.
