Highly selective production of renewable p-xylene from bio-based2,5-dimethylfuran and ethylene over Al-modified H-Beta zeolites
p-xylene ethylene Al-modified H-Beta zeolites
2023/6/19
Highly selective synthesis of renewable p-xylene (PX) from bio-based 2,5-dimethylfuran (DMF) and ethylene was successfully realized on H-Beta zeolite catalysts with further Al-modifications. The influ...
Effects of crystallinity of ZSM-5 zeolite on para-selective tert-butylation of ethylbenzene（图）
ZSM-5, Fluoride medium p-selectivity Ethylbenzene Tert-butylation, Zeolite
2013/9/27
Highly crystalline ZSM-5 zeolites are important for para-selective alkylation of alkyl aromatics, because they carry few external acid sites for isomerization of p-dialkyl products. Such zeolites (Si/...
Solvent-Free Selective Cross-Aldol Condensation of Ketones with Aromatic Aldehydes Efficiently Catalyzed by a Reusable Supported Acidic Ionic Liquid（图）
cross-aldol condensation solvent-free condition supported acidic ionic liquid ketone aromatic aldehyde
2013/10/4
A newly prepared catalyst consisting of acidic ionic liquid 1-(4-sulfonic acid)butylpyridinium hydrogen sulfate supported on silica was used to catalyze the cross-aldol condensation of ketones with ar...
Selective Oxidation of Diphenylmethane to Benzophenone over CeAlPO-5 Molecular Sieves（图）
CeAlPO-5 molecular sieve hydrothermal synthesis oxidation diphenylmethane benzophenone
2013/10/7
Selective oxidation of diphenylmethane to benzophenone requires active and selective catalysts. The framework incorporation of cerium in AlPO-5 molecular sieves creates active cerium sites in isolatio...
The Role of Vanadia for the Selective Oxidation of Benzyl Alcohol over Heteropolymolybdate Supported Alumina Catalysts（图）
molybdophosphoric acid vanadia alumina oxidation benzyl alcohol
2013/10/10
A series of 12-molybdophosphoric acid (MPA) supported on V2O5 dispersed γ-Al2O3 catalysts with different vanadia loadings were prepared by impregnation and characterized by N2 adsorption-desorption, X...
Rh/ZnO-Al2O3 Catalysts for Selective Hydrogenation of Crotonaldehyde（图）
rhodium-based catalyst crotonaldehyde hydrogenation zinc oxide selectivity
2013/10/12
Gas phase hydrogenation of crotonaldehyde was performed over 1 wt% Rh/ZnO-Al2O3 catalysts with various Zn/Rh atomic ratios. Monometallic Rh/Al2O3 was also prepared for comparison. The samples were pre...
Heterogeneization of [Cu(2,2'-bpy)Cl2] and [Cu(1,10-phen)Cl2] on Polyoxometalates: New Catalysts for the Selective Oxidation of Tetralin（图）
tetralin partial oxidation Cu(II) complexes 2,2'-bipyridine 1,10-phenantroline hydrogen peroxide polyoxometalate
2013/10/13
Mononuclear Cu(II) bipyridine (1) and phenantroline complexes (2) were synthesized and immobilized by different procedures on H3PW12O40 polyoxometalate (POM). Characterization by XRD and SEM-EDX were ...
Identification of Active Sites and Influence of Real Structure of Gold Catalysts in the Selective Hydrogenation of Acrolein to Allyl Alcohol
Gold Catalysts Selective Hydrogenation
2009/7/29
We have successfully employed oxide supported gold
catalysts in the gas-phase hydrogenation of acrolein, the
,-unsaturated aldehyde being most difficult to
hydrogenate at the carbonyl group. The ...
