Potassium benzoate Wikipedia

A process for preparing benzoic acid by oxidizing toluene with a molecular oxygen containing gas in the liquid phase, which is characterized in that the oxidation is performed in the substantial absence of lower fatty acids and/or halogen compounds, and in the presence of a catalyst composed of component A which is a nickel compound, and. 2/09/1975В В· A process for preparing benzoic acid by oxidizing toluene with a molecular oxygen containing gas in the liquid phase, which is characterized in that the oxidation is performed in the substantial absence of lower fatty acids and/or halogen compounds, and in the presence of a catalyst composed of component A which is a nickel compound).

This page gives details of some reactions of benzene and methylbenzene (toluene) not covered elsewhere in this section. It deals with the combustion, hydrogenation and sulphonation of benzene and methylbenzene (toluene), and with the oxidation of side chains attached to benzene rings. Addition of TiO2 to soil raised the yield of the acid, implying such a metal oxide plays a real catalytic role in this oxidation. By these supplementary experiments, one of the possibilities for the formation of benzoic acids in natural soil from benzyl chlorides was supported.

Benzene, benzophenone, toluene and benzyl alc. are byproducts in selective redn. of benzoic acid to benzaldehyde on ZnO and ZrO2 catalyst. The pathways to the byproducts are discussed and a complete overview of the reaction network is presented. Benzene and benzophenone are products of the decompn. of the strongly adsorbed benzoic acid at elevated temps. Toluene is formed by deoxygenation of

Preparation of benzene, compiled by CHROMIUM, special contributions by IPN, ORDENBLITZ, S.C. W ACK, and ORGANIKUM Introduction This is an extract of the benzene thread: Aromatic Side Chain Oxidation: Preparation of a Benzoic Acid Derivative A. Background Benzoic acid and its derivatives are important building blocks in organic chemistry. The sodium salt of benzoic acid is best known for its use as a food preservative where it provides antimicrobial properties. Currently, the maximum allowed level of sodium benzoate in a food product is 0.1% weight percent

The changes in the concentration of toluene and its products benzyl alcohol, benzaldehyde, benzoic acid, benzyl benzoate, trans-stilbene and methyl biphenyl carboxylic acid were monitored by UV–VIS spectroscopy, gas chromatography and thin layer chromatography [15, 16, 21, 22].
