Adipic acid is an organic acid that contains six carbon atoms, and also has two carboxylate groups (-COOH) attached to the terminal carbons in the chain. Adipic acid otherwise rarely occurs in nature,[4] but it is known as manufactured E number food additive E355. Adipic Acid. It has also been incorporated into the polymeric coating of hydrophilic monolithic systems to modulate the intragel pH, resulting in zero-order release of a hydrophilic drug.

The Merck Index* Online | Adipic Acid | Monograph containing literature references, physical and biological properties and relevant information Beilstein/REAXYS Number 1209788 . Adipic acid is produced from a mixture of cyclohexanone and cyclohexanol called KA oil, the abbreviation of ketone-alcohol oil. Another method is oxidative cleavage of cyclohexene using hydrogen peroxide. https://www.canada.ca/.../hazardous-substance-assessments/adipic-acid.html Cyclohexanone is the key intermediate for the production of adipic acid, an important compound for the synthesis of nylon 66. Adipic Acid. Adipic acid has been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basic and weakly acidic drugs. 1071-93-8 - IBVAQQYNSHJXBV-UHFFFAOYSA-N - Adipic acid dihydrazide - Similar structures search, synonyms, formulas, resource links, and other chemical information. Theoretical yield = 0.019 mol adipic acid x 146 g adipic acid . From an industrial perspective, it is the most important dicarboxylic acid: about 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon. Images e.g. 124-04-9 - WNLRTRBMVRJNCN-UHFFFAOYSA-N - Adipic acid [NF] - Similar structures search, synonyms, formulas, resource links, and other chemical information. Adipic acid, despite its name (in Latin adipis is fat), is a product of the oxidative rancidity of fats (lipid peroxidation).. Adipic acid consumption is linked almost 90% to nylon (nylon-6.6) production by the polycondensation with 1,6-hexamethylenediamine. Adipic Acids as Quality Control of Cyclohexanone Production . 607-144-00-9 - REACH : Registration number 01-2119457561-38-0009 The key difference between adipic acid and salicylic acid is that adipic acid contains two carboxyl acid groups, whereas salicylic acid contains one carboxyl acid group per molecule.. Adipic acid and salicylic acid are organic compounds. Synonym: 1,2-Benzenedicarboxylic acid 1,2-dihexyl ester, Di-n-hexyl phthalate, Phthalic acid dihexyl ester Empirical Formula (Hill Notation): C 20 H 30 O 4 Molecular Weight: 334.45 This means it has a total of 6 carbons, 10 hydrogens and 4 oxygens. Adipic acid was first obtained by Dieterle and his colleagues in 1884 by oxidation of castor oil with nitric acid. Fairfield Conn., 33(15), 2001, 18-21. https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:30832, ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agency’s EPISuite™, Compounds with the same molecular formula, Search Google for structures with same skeleton, 265 C / 100 mmHg (365.4998 °C / 760 mmHg), 265 °C / 100 mmHg (365.4998 °C / 760 mmHg), white crystals or crystalline powder; practically odourless; aqueous phase has a pleasant sour taste.
