Description
Cyclohexanecarboxylic acid, also known as hexahydrobenzoic acid or carboxycyclohexane, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Cyclohexanecarboxylic acid is a weakly acidic compound (based on its pKa). Cyclohexanecarboxylic acid exists in all living organisms, ranging from bacteria to humans. Cyclohexanecarboxylic acid is an acidic, cheese, and fruity tasting compound. Outside of the human body,. A monocarboxylic acid that consists of cyclohexane substituted by a carboxy group.
Application
Cyclohexanecarboxylic acid is a precursor to the nylon-6 precursor caprolactam via its reaction with nitrosylsulfuric acid. It can also be oxidized to cyclohexene.
Cyclohexanecarboxylic acid exhibits the reactions typical of carboxylic acids, including its conversion to the acid chloride cyclohexanecarbonyl chloride.
Chemical Properties
White crystalline solid
Chemical Properties
Cyclohexanecarboxylic acid has a cheese-like odor.
Uses
Cyclohexanecarboxylic acid can be used to determine complex binding constants of the three native cyclodextrins with seven cyclohexane derivatives.
Uses
Paint and varnish driers, dry-cleaning soaps,
lubricating oils, stabilizer for rubber.
Uses
Cyclohexanecarboxylic acid may be used as an analytical standard for the determination of the analyte in wine and other alcoholic beverages, edible salts and high-salinity foods, and ethanolic extract of
Centella asiatica by various analytical techniques.
Definition
ChEBI: A monocarboxylic acid that consists of cyclohexane substituted by a carboxy group.
Taste threshold values
Taste characteristics at 5 ppm: fruity, woody, berry-like with green dirty nuances
General Description
Cyclohexanecarboxylic acid, the saturated analog of benzoic acid, is categorized under the family of volatile organic compounds (VOCs). It is typically used as a flavoring ingredient.
Biochem/physiol Actions
Cyclohexanecarboxylic acid undergoes microbial degradation by a strain of Antherobacter to form para-hydroxybenzoic acid. Cyclohexanecarboxylic acid undergoes aromatization and converts to Hippuric acid in rat liver extracts in vitro. Cyclohexanecarboxylic acid is the starting reagent for the synthesis of polyketide-type antibiotics, Phoslactomycins.
Purification Methods
Crystallise the acid from hot H2O (solubility is 0.2% w/w at 15o), it is soluble in organic solvents. Also distil it at as high a vacuum as possible and warm the condenser as it solidifies on cooling.The acid chloride M 146.6, has b 184o/atm, d2 5 1.096, the methyl ester has b 183o/atm, and the S-benzylisothiuronium salt
has m 165-166o (from EtOH). [Beilstein 9 H 7, 9 I 5, 9 II 6, 9 III15, 9 IV 16.]
