Other isomers of cyclohexanedicarboxylic acid are known, but the 1,4- isomers are of greatest interest, perhaps because they are obtainable from a commodity chemical. Specifically, hydrogenation of terephthalic acid affords the title compound: [1] C 6 H 4 (CO 2 H) 2 + 3 H 2 → C 6 H 10 (CO 2 H) 2. The trans isomer has been more heavily studied.
The molecular formula C 8 H 12 O 4 (molar mass: 172.178 g/mol) may refer to: ... 1,4-Cyclohexanedicarboxylic acid This page was last edited on 1 March 2023, at 10:49 ...
Cyclohexanecarboxylic acid is a precursor to the nylon-6 precursor caprolactam via its reaction with nitrosylsulfuric acid. It can also be oxidized to cyclohexene. [2] Cyclohexanecarboxylic acid exhibits the reactions typical of carboxylic acids, including its conversion to the acid chloride cyclohexanecarbonyl chloride. [3] [4]
In organic chemistry, a dicarboxylic acid is an organic compound containing two carboxyl groups (−COOH).The general molecular formula for dicarboxylic acids can be written as HO 2 C−R−CO 2 H, where R can be aliphatic or aromatic.

1,2-Cyclohexane dicarboxylic acid diisononyl ester (DINCH) is a mixture of organic compounds with the formula C 6 H 10 (CO 2 C 9 H 19) 2. DINCH is colorless oil. DINCH is colorless oil. It is used as a plasticizer for the manufacture of flexible plastic articles in sensitive application areas such as toys, medical devices, and food packaging.
A copper chromite catalyst is usually used industrially. [1] The cis/trans ratio of the CHDM is affected by the catalyst. [2] Byproduct of this process are 4-methylcyclohexanemethanol (CH 3 C 6 H 10 CH 2 OH) and the monoester methyl 4-methyl-4-cyclohexanecarboxylate (CH 3 C 6 H 10 CO 2 CH 3, CAS registry number 51181-40-9).

Cyclododecatriene is the raw material for the production of dodecanedioic acid (4) through hydrogenation to cyclododecane (2) followed by air oxidation in the presence of boric acid at elevated temperatures to a mixture of the alcohol (3a) and the ketone (3b).
