The reaction could be efficiently accelerated by IrI4 catalyst and LiI promoter in AcOH solvent at 170 °C, and the yield of C5 carboxylic acids reached 70% after 16 h (entry 1). The products contained two isomers, i.e., pentanoic acid and 2-methylbutanoic acid, and their molar ...
The carboxylic acid26and the corresponding methyl andethyl esters27–29(Fig. 10), each incorporating a calamiticterphenylunit, were investigated with respect to their thermal bulk properties, the monolayer behavior, and their ability to form Langmuir-Blodgett multilayers [68]. ...

Carboxylic acid - Properties, Structure, Reactions: The most important property of carboxylic acids, and the one that is responsible for naming them such, is their acidity. An acid is any compound that donates a hydrogen ion, H+ (also called a proton), t
Carboxylic acidderivativeshave varied applications. For example, in addition to its use as a disinfectant,formic acid, the simplest carboxylic acid, is employed intextiletreatment and as an acid reducing agent.Acetic acidis extensively used in the production of celluloseplasticsand esters.Aspirin, the...
