Mechanism of the vapor-phase dehydration of cyclohexanol to cyclohexanone on a copper-magnesium catalystStudy has been made of the hydrogen-deuterium exchange, in cyclohexanol under dehydrogenation conditions and in cyclohexanone under hydrogenation conditions, on a copper-magnesium cataiyst. The overall ...
In the current research, a novel green double layer coating technology with LPU as the inner coating and EP as the outer coating was effectively constructed for coated urea. The impacts of lignin content, –CNO/–OH molar ratio, amount of EP, and coating ratio on the nutrient release of li...
They found that RANEY Ni acts as the hydrogenation catalyst, resulting in cyclohexane/alkylcylcohexane being the dominant products formed from full hydrogenation of the aromatic ring, while Nafion/SiO2 acts as the Brønsted solid acid for hydrolysis and dehydration. Sun et al. compared HDO of ...
By means of deuterium labelling experiments, the mechanism of the gas-phase dehydration of cyclohexanol over a solid zirconium phosphate catalyst has been shown to involve a carbocation with a long lifetime. Product distribution studies have been used to show that the corresponding dehydrations of ...
The rate of acid–base-catalyzed dehydration of alcohols strongly depends on the solvent and the environment of the acid sites. We find that Br?nsted acidic sites in large-pore zeolites, but not in medium-pore zeolites, catalyze cyclohexanol dehydration in decalin at significantly higher rates ...
