Dicarboxylic acid - Wikipedia
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 HO2C−R−CO2H, where R can be aliphatic or aromatic. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids.
25.1 Carboxylic Acids – Structure and Naming
Dicarboxylic Acids A dicarboxylic acids is an organic compound containing two carboxyl groups (-COOH) often referred to as a diacid. The general molecular formula for dicarboxylic acids can be written as HO−R−COOH.
17.23: Dicarboxylic Acids and Their Derivatives
Structure of the carboxyl acid group. Carboxylic acids are organic compounds which incorporate a carboxyl functional group, CO 2 H. The name carboxyl comes from the fact that a carbonyl and a hydroxyl group are attached to the same carbon. The carbon and oxygen in the carbonyl are both sp2 hybridized which give a carbonyl group a basic trigonal ...

2021年7月31日 · A number of important dicarboxylic acids are listed in Table 18-4 together with their physical properties, methods of manufacture, and commercial uses. The inductive effect of one carboxyl group is expected to enhance the acidity of the other.
Dicarboxylic Acid - an overview | ScienceDirect Topics
Dicarboxylic acids are solids at room temperature and they have melting points that are higher than those of monocarboxylic acids containing the same number of carbon atoms, since stronger associations between molecules exist, mainly as a result of hydrogen bond formation.

2020年8月11日 · Carboxylic acids are converted to acid chlorides by a range of reagents: SOCl 2, PCl 5 or PCl 3 are the usual reagents. Other products are HCl & SO 2 , HCl & POCl 3 and H 3 PO 3 respectively. The conditions must be dry, as water will hydrolyse the acid chloride in a …
Oxalic acid (COOH)2 - Formula, Properties, Structure & Uses …
Oxalic acid is a dicarboxylic acid with the chemical formula C2H2O4. Oxalic acid occurs in the cell sap of Oxalis and Rumex species of plants as potassium and calcium salt. In an aqueous solution, oxalic acid is a weak acid that will only partially ionise. Oxalic acid has two acidic protons.
Dicarboxylic Acid - an overview | ScienceDirect Topics
The molecular formula for dicarboxylic acids is HOOC (CH2) n COOH; where n is 0 for oxalic acid, 1 for malonic acid, 2 for succinic acid, 3 for glutaric acid, 4 for adipic acid, etc. Dicarboxylic acid can yield two kinds of salts or esters, as it contains two carboxyl groups in its molecules.
