oxidation of benzaldehyde to benzoic acid

Dodecatungstophosphoric acid was synthesized and used as catalyst for oxidation of benzaldehyde to benzoic acid with aqueous hydrogen peroxide. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Synth Comm 36:679–683. https://doi.org/10.1016/j.cattod.2012.02.020, CAS  In CH3OH, benzaldehyde was selectively oxidized to benzoic acid and posteriorly esterified to methyl benzoate. Reaction of benzaldehyde with anhydrous sodium acetate and acetic anhydride yields cinnamic acid, whil… Angew Chem Int Ed 48:9038–9049.

The first reaction produced benzoin by using the thiamine hydrochloride catalyst, followed by an oxidation reaction to produce benzil, and a rearrangement to synthesize benzilic acid. When benzoic acid is reacted with soda lime (mixture of NaOH and CaO) with heat, it results in the formation of benzene. A mechanism is proposed both for this reaction, and for the asymmetric addition of HCN to aldehydes catalysed by this peptide based on a common intermediate for bothreactions.

Chemical Papers 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. One-pot synthesis of benzaldehyde derivatives in PdCl2-catalyzed reactions with H2O2 in alcoholic solutions. Wiley Online Library. In this experiment potassium permanganate is used to oxidize benzaldehyde giving the reaction of C6H5CHO + MnO^- 4 + OH-  C6H5COO- + MnO2 + H2O. In CH3OH, benzaldehyde was selectively oxidized to benzoic acid and posteriorly esterified to methyl benzoate. Benzilic acid was synthesized through a multistep reaction from the starting material of benzaldehyde and through the formations of benzoin and benzil. With H2O2 at an equimolar ratio, the Pd(0) reduced the benzaldehyde to benzyl alcohol (30%). https://doi.org/10.1016/j.cattod.2014.03.004, Sedelmeier J, Ley SV, Baxendale IR, Baumann M (2010) KMnO4-mediated oxidation as a continuous flow process. https://doi.org/10.1002/aoc.949, Viana LAS, da Silva GRN, da Silva MJ (2018) A highly selective Na2WO4-catalyzed oxidation of terpenic alcohols by hydrogen peroxide. https://doi.org/10.1016/S1381-1169(02)00195-4, Rubio-Caballero JM, Saravanamurugan S, Maireles-Torres P, Riisager A (2014) Acetalization of furfural with zeolites under benign reaction conditions.

The cyclic dipeptide cyclo-[(S)-His-(S)-Phe] is found to catalyse the oxidation of benzaldehyde to benzoic acid. In CH3OH, benzaldehyde was selectively oxidized to benzoic acid and posteriorly esterified to methyl benzoate. Below is the link to the electronic supplementary material. Under basic conditions, the permanganate is reduced to manganese dioxide, and the benzaldehyde is oxidised to the benzoate ion (rather than straight to benzoic acid, as it would under acidic conditions). de Moçambique, Km 1, 4040, Maputo, Mozambique, You can also search for this author in The activity of the palladium salt catalysts was investigated on the benzaldehyde reactions with H2O2.
