Dicarboxylic acids where the carboxylic groups are separated by none or one carbon atom decompose when they are heated to give off carbon dioxide and leave behind a monocarboxylic acid. [26] Blanc's Rule says that heating a barium salt of a dicarboxylic acid, or dehydrating it with acetic anhydride will yield a cyclic acid anhydride if the ...
Acetylenedicarboxylic acid or butynedioic acid is an organic compound (a dicarboxylic acid) with the formula H 2 C 4 O 4 or HO−C(=O)−C≡C−C(=O)−OH. It is a crystalline solid that is soluble in diethyl ether .
Dibasic ester or DBE is an ester of a dicarboxylic acid.Depending on the application, the alcohol may be methanol or higher molecular weight monoalcohols. Mixtures of different methyl dibasic esters are commercially produced from short-chain acids such as adipic acid, glutaric acid, and succinic acid. [1]
In chemistry, 2,2,3,3-tetramethylsuccinic acid or 2,2,3,3-tetramethylbutane-1,4-dioic acid is a dicarboxylic acid with the formula C 8 H 14 O 4, or HOOC-C(CH 3) 2-C(CH 3) 2-COOH. [1] [2] It can be seen as derivative of succinic acid (butane-1,4-dioic acid) with two methyl groups replacing two hydrogen atoms on each of the central carbon atoms ...
Adipic acid is produced by oxidation of a mixture of cyclohexanone and cyclohexanol, which is called KA oil, an abbreviation of ketone-alcohol oil. Nitric acid is the oxidant. The pathway is multistep. Early in the reaction, the cyclohexanol is converted to the ketone, releasing nitrous acid: HOCH(CH 2) 5 + HNO 3 → O=C(CH 2) 5 + HNO 2 + H 2 O
Acetonedicarboxylic acid, 3-oxoglutaric acid or β-ketoglutaric acid is a simple dicarboxylic acid with the formula O=C(CH 2 CO 2 H) 2. β-Ketoglutarate does not have the biological activity exhibited by α-ketoglutarate.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Simplified structural formula of a dimer fatty acid. The structure may vary depending on the raw materials used. Characteristic is the cyclohexene ring formed by the Diels-Alder reaction. Dimer acids, or dimerized fatty acids, are dicarboxylic acids prepared by dimerizing unsaturated fatty acids obtained from tall oil, usually on clay catalysts.
