Selective Liquid Phase Ammoxidation of Aromatic Aldehydes to Aromatic Nitriles with VPO Titania Heterogeneous Catalysts in Air
Preparation of 2-Chlorobenzonitrile, and benzonitrile are reported here from the corresponding 2-Chlorobenzaldehyde and benzaldehyde by the reaction of ammonium hydroxide/VPO titania, VPO bulk (...
متن کاملKinetic Studies of the Catalytic Oxidation of Toluene to Benzoic Acid in the Liquid Phase
The catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. Low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. The dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. It has been suggested that liquid phase oxidation of t...
متن کاملSelective Oxidation of Lauryl Alcohol to Lauraldehyde under Liquid-Liquid Phase Transfer Catalysis (LL-PTC) with Potassium Chromate as the Oxidizing Agent
In the present research, the selective oxidation of lauryl alcohol to lauraldehyde was studied under liquid-liquid phase transfer conditions using potassium chromate (K2CrO4) as an oxidizing agent and tetrabutyl ammonium bromide (TBAB) as the phase transfer catalyst. Chromium (VI) reagents are used in these oxidations since the alcohols are selectively oxidized <e...
متن کاملLiquid-Phase Oxidation of p-Xylene using N-Hydroxyimides
In this communication, we describe p-xylene oxidation with molecular oxygen at 373 K and atmospheric pressure using N-hydroximide catalysts. p-Xylene conversion was rather high over the first 2 h of reaction and complete by the end of the experiment. The product distribution curves versus reaction time are typical of consecutive reactions. The main intermediate product is p-toluic acid. Peak co...
متن کاملPd on carbon nanotubes for liquid phase alcohol oxidation
Pd nanoparticles supported on carbon nanotubes (CNTs) showed a higher selectivity than Pd nanoparticles supported on activated carbon (AC) in the liquid phase oxidation of benzylic alcohol to benzaldehyde. Under solventless conditions a significant improvement in selectivity was observed for Pd/CNTs, whereas using Pd/AC a considerable over-oxidation of benzaldehyde was observed. Differently fro...
