Dicarboxylic Acids

Abstract

Aliphatic, linear dicarboxylic acids and branched dicarboxylic acids are the subject of this article. These dibasic acids are referred to by their trivial names, IUPAC system or by adding the suffix “dicarboxylic acid“ to the name of the hydrocarbon skeleton. For example a 10‐carbon atom dibasic acid is designated sebacic acid, decanoic or 1,8‐octane‐dicarboxylic acid. Physical and chemical properties of the most common dibasic acids are discussed. Manufacture and uses for glutaric acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, dodecanoic acid, brassylic acid and C‐19, C‐20, and C‐22 dicarboxylic acids are given. These diacids are intermediates for the manufacture of diesters, polyesters, and polyamides. These derivatives have many applications ,eg, as plasticizing agents, lubricants, heat‐transfer fuids, inks and coatings, insecticides. Azaleic acid is used in acne preparations. Toxicities and environmental concerns are also discussed.

Enzymatic bulk synthesis, characterization, rheology, and biodegradability of biobased 2,5-bis(hydroxymethyl)furan polyesters

“…This could be attributed to the fact that the melting points of even linear saturated aliphatic dicarboxylic acids are generally higher than those of odd carbon diacids, which is related to the in-plane orientation of the carbonyl groups. 53 This might lead to more favorable interactions between the chains and therefore a higher degree of crystallinity.…”

Liquid phase oxidation of cyclopentanone over metal-free carbon catalysts

“…Industrially, GA was produced in the past as a side product in the production of adipic acid (Johnson et al 2010). Other possibility is the oxidation of cyclopentanone (CPO, CAS:120-92-3) and cyclopentanol (CPL, CAS:96-41-3) by concentrated nitric acid, or by the carbonylation of butyrolactone (Johnson et al 2010).…”

In recent years biotechnological procedures are intensively developed for the production of GA, or generally, the so called C5 platform chemicals (Park et al 2013, Rohles et al 2018, Kim et al 2019, Han et al 2020.…”

Regioselective Coupling of Different Conjugate Esters by Magnesium Metal Reduction: A Route to Unsymmetrical Adipic Acid Esters

“…Adipic acid esters are significant compounds that are widely used as raw materials of polymers, plasticizers, and lubricants in industry . Traditional approaches to synthesize adipic acid esters in industry start from the hydrogenation of petroleum-derived benzene, followed by multiple oxidation steps (Scheme a, i) .…”
