Kinetics and mechanism of coupled synthesis of cyclohexanecarboxylic acid

Russian Journal of Physical Chemistry A, 2015
The effect of the nature of the anion in a palladium salt on a coupled process involving the oxidation of CO and hydrocarboxylation of cyclohexene in the PdX2-CuBr2-THF-H2O system was studied. The kinetics was investigated under the steady-state conditions.

Degradation of cyclohexanecarboxylic acid as a model naphthenic acid by the UV/chlorine process: Kinetics and by-products identification

Journal of Hazardous Materials, 2021
Degradation kinetics, by-products identification and pathways of a model naphthenic acid, cyclohexanecarboxylic acid (CHA), by the UV/Chlorine process were investigated in this study. Mathematical modeling indicated that the initial CHA decay rate increased rapidly with the chlorine dose when the chlorine dose was lower than 45 mg/L and decreased with ...

Oxidative decarboxylation of cyclohexanecarboxylic acid

Recueil des Travaux Chimiques des Pays-Bas, 1963
AbstractCyclohexanecarboxylic acid is converted to a mixture of cyclohexanone and cyclohexene by reacting it at temperatures around 200° with an oxygen‐containing gas and steam in the presence of metal‐salt catalysts.

Conformation and reactivity. Part VI. Kinetics of the acid-catalysed esterification in methanol of the trans-decalincarboxylic acids, of the 4-t-butyl- or 2-methyl-cyclohexanecarboxylic acids, of certain trans-4-substituted cyclohexanecarboxylic acids, and of cyclohexanecarboxylic acid

Journal of the Chemical Society B: Physical Organic, 1967
The rates of acid-catalysed esterification in methanol at 30° of the trans-decalincarboxylic acids, of cis- and trans-4-t-butylcyclohexanecarboxylic acid, of cis- and trans-2-methylcyclohexanecarboxylic acid, of trans-4-X-cyclohexanecarboxylic acids (X = OH, CO2Et, CO2Me, Br, or CN), and of cyclohexanecarboxylic acid have been measured.

The Metabolism of Cyclohexanecarboxylic Acid in the Isolated Perfused Rat Liver

Xenobiotica, 1977
1. Cyclohexanecarboxylic acid in isolated perfused rat livers was eliminated from the perfusion system by a first-order process. 2. After 6 h, 16% was excreted in bile as cyclohexylcarbonyl beta-D-glucuronide. The remainder was present in the perfusate as unchanged cyclohexanecarboxylic acid (10%), hippuric acid (50%), hexahydrohippuric acid (2%), 3,4 ...

Conformation and reactivity. Part V. Kinetics of the esterification with diazodiphenylmethane in methanol, ethanol, or t-pentyl alcohol of the trans-decalincarboxylic acids, of the 4-t-butyl- or 2-methyl-cyclohexanecarboxylic acids, of certain trans-4-substituted cyclohexanecarboxylic acids, and of cyclohexanecarboxylic acid

Journal of the Chemical Society B: Physical Organic, 1967
The rates of esterification with diazodiphenylmethane in methanol, ethanol, or t-pentyl alcohol at 30° of the trans-decalincarboxylic acids, of cis- and trans-4-t-butyl-, cis- and trans-2-methyl-cyclohexanecarboxylic acid, of trans-4-X-cyclohexanecarboxylic acid (X = OH, CO2Et, CO2Me, Br, or CN), and of cyclohexanecarboxylic acid have been measured ...

The microbial degradation of cyclohexanecarboxylic acid: a pathway involving aromatization to form p-hydroxybenzoic acid

Canadian Journal of Microbiology, 1974
A strain of Arthrobacter catabolizes cyclohexanecarboxylic acid by a pathway involving aromatization of the ring before its cleavage. The pathway includes the following intermediates: trans-4-hydroxycyclohexanecarboxylic acid, 4-ketocyclohexanecarboxylic acid, p-hydroxybenzoic acid, protocatechuic acid, and β-ketoadipic acid.

Origin of cyclohexanecarboxylic acid in Bacillus acidocaldarius

Phytochemistry, 1974
Abstract In Bacillus acidocaldarius , shikimic acid is converted into the cyclohexancearboxylic acid precursor of fatty acids by way of cyclohexene-l-carboxylic acid, but not by way of cyclohexene-3- or -4-carboxylic acid or benzoic acid.
