摘要: The kinetics of the catalytic hydrodeoxygenation phenol and substituted phenols has systematically been investigated on dual-functional catalyst system Pd/C H(3)PO(4) in order to better understand elementary steps overall reaction. reaction proceeds via stepwise hydrogenation aromatic ring, transformation cyclic enol corresponding ketone, cycloalkanone cycloalkanol its subsequent dehydration as well formed cycloalkene. presence dual functions is indispensible for hydrodeoxygenation. significantly slower than keto/enol transformation, requiring a larger concentration Bronsted acid sites compared available metal hydrogenation.
