Neodecanoic acid (NDA) is a mixture of carboxylic acids with the common chemical formula C10H20O2. NDA is a colorless liquid with a relatively low vapor pressure and it's widely used in industrial synthesis processes. As mixture of constitutional isomers, we can identify some properties shared with trialkyl acetic acid by the following isomers:{{Cite web|url=https://www.journalssystem.com/ppmp/pdf-51291-15255?filename=Neodecanoic%20acid%20as%20an.pdf|website=www.journalssystem.com|title= NEODECANOIC ACID AS EXTRACTANT OF SELECTED|language=en|access-date=2025-05-21}}{{Cite web|url=https://www.atamanchemicals.com/neodecanoic-acid_u32507/|website=www.atamanchemicals.com|title= NEODECANOIC ACID |language=en|access-date=2025-05-21}}
Properties
=Acidity=
The proton of the carboxyl group (−COOH) of Neodecanoic acid can be separated with the reaction proceeding as follows:
:{{chem2|RCOOH ⇌ RCO2− + H+}}
With R being any aliphatic groups with 9 carbon atoms. Thanks to the release of the proton Neodecanoic acid have a weak acidic character. Being a monoprotic acid, it has only one dissociation, with the pKa of the strongest acid form valued at 5.17.{{Cite web|url=https://foodb.ca/compounds/FDB007903|title= Showing Compound Neodecanoic acid (FDB007903)|language=en|access-date=2025-05-22}}
