چکیده

The aerobic oxidation of organic molecules and in particular alcohols bio-derived poly to value-added commodity is under continuous investigation, due the importance products (aldehydes, ketones carboxylic acids esters) challenging nature this chemical transformation, since rather harsh reaction conditions (T > 100 °C) are needed gain a significant substrate conversion [...]

Selective 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...

Serial ligand catalysis: a highly selective allylic C-H oxidation.

We are reporting a mild, chemo-, and highly regioselective Pd(II)-catalyzed allylic oxidation of alpha-olefins to furnish branched allylic esters that proceeds via a novel serial ligand catalysis mechanism in which two different ligands (i.e., vinyl sulfoxide 2 and BQ) interact sequentially with the metal to promote distinct steps of the catalytic cycle (i.e., C-H cleavage and pi-allyl function...

Reactivity of the gold/water interface during selective oxidation catalysis.

The selective oxidation of alcohols in aqueous phase over supported metal catalysts is facilitated by high-pH conditions. We have studied the mechanism of ethanol and glycerol oxidation to acids over various supported gold and platinum catalysts. Labeling experiments with (18)O(2) and H(2)(18)O demonstrate that oxygen atoms originating from hydroxide ions instead of molecular oxygen are incorpo...

Alcohol selective oxidation over modified foam-silver catalysts

Catalysts based on silver supported on foam ceramics and modified by Zr, Ce and La oxides have been studied in the process of partial oxidation of methanol to formaldehyde. The foam catalysts exhibit high catalytic, mechanical and gas -dynamic properties exceeding the characteristics of conventional crystalline and supported silver samples. Modifying additives of Zr and Ce oxides raise activity...
