Upgrading of diols by gas-phase dehydrogenation and dehydration reactions on bifunctional...

Biomass-derived short-chain polyols can be transformed into valuable oxygenates used as building blocks. The gas phase conversion of a model molecule of 1,3-diols (1,3-butanediol), was studied on bifunctional Cu-Mg, Cu-Al and Cu-Mg-Al mixed oxide catalysts that exhibit surface Cu0 particles and acid-base properties.A series of ZCuMgAl catalysts (Z = 0.3-61.2 wt.% Cu, Mg/Al = 1.5 molar ratio) was prepared by coprecipitation and thoroughly characterized by several techniques such as...

Conversion of diols by dehydrogenation and dehydration reactions on silica-supported...

The gas-phase conversion of a 1,3-polyol (1,3-butanediol) containing primary and secondary OH functions was studied on a series of copper-silica catalysts, ZCuSiO2 (Z = 1-25 wt.% Cu), and thoroughly characterized by several techniques such as BET surface area, TPR, XRD, N2O chemisorption, and UV-vis-DRS. The physicochemical properties of the ZCuSiO2 catalysts depended on whether the metal loading was above or below the copper monolayer surface coverage (Z = 13.5 wt.% Cu)....

Gas-phase conversion of 1,3-butanediol on single acid-base and Cu-promoted oxides

The gas-phase conversion of 1,3-diols was studied on catalysts containing different active sites and using1,3-butanediol as a model molecule. Transformation of the diol primary and/or secondary OH groups by dehydration and dehydrogenation reactions yields valuable oxygenates combining OH and C=C, OH and C=O or C=C and C=O functions, along with other compounds. A series of single oxides with different acid-base properties, copper-silica and copper-single oxide catalysts were prepared by...

Gas-phase reduction of cyclic and acyclic α,β-unsaturated ketones by hydrogen...

The gas-phase hydrogen transfer reduction (HTR) of cyclic and acyclic α,β-unsaturated ketones to the corresponding unsaturated alcohols (UOL) using 2-propanol as hydrogen donor was studied on MgO as an alternative to the less selective conventional hydrogenation using high pressure H2. The HTR of 2- cyclohexenone and mesityl oxide were used as model reactions. The MgO activity and selectivity toward the unsaturated alcohol depended on ...

Effect of MgO activation conditions on its catalytic properties for base-catalyzed reactions

The effect of the MgO calcination temperature on its basicity and catalytic properties was studied. Three MgO samples calcined at 673, 773 and 873 K (samples MgO-673, MgO-773 and MgO-873) were characterized by different physical and spectroscopic techniques. The surface base properties were probed by temperature-programmed desorption of CO2 and infrared spectroscopy after CO2 adsorption at 298 K...

Process for the production of vegetable oils rich in 1,3-diacylglycerols

A process for obtaining vegetable oil rich in 1,3- diacylglycerols with at least 10% by weight of 1,3- diacylglycerols comprising a transesterification reaction of triacylglycerol and glycerin in the presence of a solid catalyst is provided. A vegetable oil rich in 1,3- diacylglycerols containing 20 to 40% by weight of 1,3- diacylglycerols is also provided.
