Cyclohexanecarboxylic acid Usage And Synthesis

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

Paint and varnish driers, dry-cleaning soaps, lubricating oils, stabilizer for rubber.

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

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).
