High catalytic activity of silicalite in gas-phase ketonisation of propionic acid.
نویسندگان
چکیده
Amorphous silica and crystalline silicalite (MFI structure) are demonstrated to be active and environmentally benign catalysts for propionic acid ketonisation at 450-500 °C to form 3-pentanone. The silicalite is particularly efficient, and its ketonisation selectivity is increased by base modification probably through generation of silanol nests.

Propionic acid extraction in a microfluidic system: simultaneous effects of channel diameter and fluid flow rate on the flow regime and mass transfer
In this work, extraction of propionic acid from the aqueous phase to the organic phase (1-octanol) was performed in T-junction microchannels and effects of channel diameter and fluid flow rate on the mass transfer characteristics were investigated. The two-phase flow patterns in studied microchannels with 0.4 and 0.8 mm diameters were observed. Weber number and surface-to-volume ratio were ca...

Coordination of Cu+ ions adsorbed on plausible sites of a silicalite-2 lattice has been investigated computationally via hybrid density functional theory method at the B3LYP/6-311+G* and B3LYP/Def2-TZVP levels of theory using molecular models of the active site. The symmetrical coordination of Cu+ ions to almost five oxygen atoms of the all-silica framework in six-membered ring (6MR) sites of t...
متن کاملMössbauer and Magnetic Studies of Iron-Zeolite and Iron-Cobalt Zeolite Catalysts Used in Synthesis Gas Conversion
Medium-pore (diameter ~ 6A) zeolites such as ZSM-5 and silicalite impregnated with Group VIII metals provide selective catalytic pathways for the conversion of synthesis gas to gasoline or olefins. Mössbauer and magnetic studies on these catalysts containing iron or iron plus cobalt are reported. The zeolites were impregnated with metal nitrate solutions, reduced, and carbided to yield showed F...
متن کاملSelective Catalytic Reduction of CuO/SiO2 Nano-composites towards NO Reduction in Gas-phase
The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7. Also, the necessary amounts of tri-hydrated copper nitrate and penta-hydrated copper sulfate were added to the solution in such a manner that the concentration of the copper oxide in final solut...

In this research, Ag/ZnO nanocomposites were prepared and characterized by transition electron microscopy (TEM), the energy dispersive X-ray spectrum (EDS) and X-ray diffraction patterns (XRD). These nanocomposites were used as catalysts for the oxidation of toluene to benzaldehyde and benzoic acid with hydrogen peroxide (H2O2) and tert-butylhydroperoxide (TBHP) as oxidizing agent in the liquid...
