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 ...
Adipic acid or hexanedioic acid is the organic compound with the formula (CH 2) 4 (COOH) 2. From an industrial perspective, it is the most important dicarboxylic acid : about 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon .
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 ...
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.
Succinic acid (/ s ə k ˈ s ɪ n ɪ k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. [5] In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ...
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.
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]
The acid is commonly traded as a laboratory chemical. It can also be reacted with sulfur tetrafluoride to produce hexafluoro-2-butyne , a powerful dienophile for use in Diels-Alder reactions . Fatty alcohol esters of acetylenedicarboxylic acid can be used for the preparation of phase change materials (PCM).
