At a reaction temperature of 393 K a conversion of propan-2-ol to diisopropyl ether and propene was observed. A 13C MAS NMR signal appearing at 220 ppm indicates the formation of ketones, probably of acetone.doi:10.1016/S0167-2991(97)80714-8M. Hunger...
Conversion of propan-2-ol in the absence of air has been used to characterize the acid–base properties of metallic oxides. Two families of solids were studied: the first, niobic acid and oxides exhibited only acidic properties, i.e. resulted only in formation of propene, the second, mixed...
Propene selectivity increases from ca. 23 to ca. 95% with the pretreatment temperature for all catalysts. The comparison of catalytic behaviour of salts for a pretreatment temperature of 200°C shows that they are selective towards DIPE and that among them, SbPMo is the most selective one (ca...
A process for producing dichloropropanol by subjecting glycerol to a reaction with a chlorinating agent in the presence of a carboxylic acid catalyst to produce dichloropropanol, where the carboxylic acid is selected from mono carboxylic acids containing 5 or 6 carbon atoms, dicarboxylic acids select...

At reaction temperatures of=373 K and=393 K a propan-2-ol conversion of 50 and 100%, respectively, and the formation of propene, diisopropyl ether, and small amounts of acetone was determined by GC. ApplyingH andC MAS NMR spectroscopy, the initial step of the reaction was found to be...

In industry, acrolein is prepared by the gas phase partial oxidation of propene over a Bi/Mo-mixed oxide catalyst. Alternatively, glycerol can be used as the feedstock to prepare acrolein via catalytic dehydration in either the gas or liquid phase. The catalysts used in the catalytic dehydration...
