Allgemeine Beschreibung
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.
läuterung methode
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).
