The carboxylic acids are themost important functional group that present C=O. This type of organic compounds can be obtained by different routes, some carboxylic acids, such ascitric acid, lactic acid or fumaric acid are produced by fermentation, most of these types of carboxylic acids are appli...
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
Nomenclatureof carboxylic acids and their salts The IUPAC name of a carboxylic acid is derived from that of the longest carbon chain that contains the carboxyl group by dropping the final -e from the name of the parent alkane and adding the suffix -oic followed by the word “acid.” The ...

Measured zeta potentials of the oil-brine interface could be represented through the sum of carboxylic acids and nitrogen bases26. In the oil/brine surface reactions, –COOH and –NH represent dangling carboxylate and nitrogen base groups present at the oil–water interface. At pH > 4.9, ...
In the HR-AMS spectra of HULIS and HP-WSOM, CHO (CxHyO1 + CxHyO>1) groups showed high contribution, whereas WISOM consisted mainly of CxHyfragments. Here, the CHO groups should represent oxygenated structures, such as, carboxylic acids, carbonyl compounds (ketones/aldehydes), alcohols, ...
ChemicalProperties of Acetic Acid The chemical reactions undergone by acetic acid are similar to those of other carboxylic acids. When heated to temperatures above 440oC, this compound undergoes decomposition to yield either methane and carbon dioxide or water and ethenone, as described by the follo...
Ten microliters of each extract were injected into a reverse phase C18 column (4.6 mm × 250 mm, 5 μm) for determination of phenolic acids and anthocyanins using Zorbax Eclipse Plus C18 (Agilent Technologies, Santa Clara, CA, USA) and to measure the γ-oryzanol content using Inertsil ODS...
