Beschreibung

Allgemeine Beschreibung

Benzoic acid (BA) is an aromatic monocarboxylic acid. It is synthesized by the oxidizing toluene with atmospheric oxygen catalyzed by cobalt and manganese catalysts.[1] It is utilized in cosmetic formulations as a pH adjuster and preservative.[2] The elimination channels during the photodissociation of benzoic acid have been studied using multimass ion imaging techniques.[3] Structural information and molecular constants have been obtained by microwave spectroscopy.[4] Crystal structure study reveals that BA crystals are monoclinic with space group P2₁/c.[5] Studies in bean and tomato plants have shown that BA induces stress tolerance at lower concentration.[6]

Anwendung

Benzoic acid (BA) may be used:

• As a model compound in understanding the adsorption of aromatic carboxylic acids on gold surfaces.[7]
• As test sample in studying the photocatalytic activities of metal doped TiO₂.[8]
• As an extracting agent of methylene blue (MB) from industrial wastewater by liquid–liquid extraction (LLE).[9]
