Benzaldehyde was oxidized to benzoic acid using Na2WO4·2H2O as a catalyst. Different factors, such as different acidic additives, the reaction time, the amount of catalyst, and hydrogen peroxide dosage, on the isolated yield of benzoic acid were investigated. The effects of surfactants on ...

The by-product benzoic acid has an autocatalytic effect on the hydration of benzaldehyde, and the subsequent oxidative dehydrogenation leads to benzoic acid, and benzyl benzoate by esterification. Promotion of Pd by Pb improves the selectivity. No catalyst deactivation or metal leaching ha 展开 ...
aAmong various oxidation transformations, the selective oxidation of toluene is a relatively simple and, nevertheless, may generate a wide range of products, such as benzyl alcohol, benzaldehyde, benzoic acid and benzyl benzoate. 在各种各样的氧化作用变革之中,甲苯的有选择性的氧化作用是一相对地简单的...
framework [MIL-100(V)] was synthesized as a heterogeneous catalyst allowing the selectivity to be switched from almost quantitative formation of benzaldehyde (Bz-CHO) to quantitative formation of benzoic acid (Bz-COOH) by changing only the temperature in the aerobic oxidation of benzyl alcohol (Bz...
The use of different solvents, dissimilar products can be obtained in the reaction: in chloroform, quantitative conversion to benzaldehyde (BnH) is achieved; while high yield is obtained when producing benzoic acid (BA) in acetonitrile. This phenomenon is related not only to the polarity of ...
oxidation of benzyl alcohol to benzaldehyde or benzoic acid under eco-friendly conditions. In this regard, a theoretical investigation was carried out to study both catalytic oxidation reaction pathways (i.e., benzyl alcohols to aldehyde and to benzoic acid) using GO as an eco-friendly and metal...
We have also found that the forming oxoiron(IV) species is capable for the oxidation of benzaldehyde to benzoic acid under argon, including rebound-type mechanism. In order to obtain more insight into the role of high-valent oxoiron(IV) intermediate on the oxidation of arylalkyl aldehydes under...
First, the solubility of different cerium(IV) salts in ILs was tested. Second, the oxidation of benzyl alcohol to benzaldehyde was studied by in-situ spectroscopic techniques (NMR, FTIR) to obtain some insight in the mechanism. Finally, the reaction was extended to other substrates, among them...
