Study Notes
Definition and Structure
- A dicarboxylic acid is a carboxylic acid that contains two carboxyl (-COOH) groups.
- General formula: HOOC-R-COOH, where R is a hydrocarbon chain.
Examples
- Oxalic acid (C2H2O4): the simplest dicarboxylic acid, found in plants and vegetables.
- Malonic acid (C3H4O4): used in the production of polyesters and alkyd resins.
- Succinic acid (C4H6O4): found in living organisms, used in the production of pharmaceuticals and biodegradable plastics.
- Glutaric acid (C5H8O4): used in the production of polyesters and polyamides.
Properties
- Dicarboxylic acids are generally more soluble in water than monocarboxylic acids.
- They have higher melting and boiling points than monocarboxylic acids due to the presence of two carboxyl groups.
- They can form complexes with metal ions, which is useful in various industrial applications.
Uses
- In the production of polymers, such as polyesters and polyamides.
- As a food additive, antioxidant, and preservative.
- In the pharmaceutical industry, as a raw material for the synthesis of certain drugs.
- In the production of biodegradable plastics and detergents.
Biological Importance
- Dicarboxylic acids play a crucial role in various metabolic pathways, such as the citric acid cycle.
- They are involved in the synthesis of amino acids, fatty acids, and cholesterol.
- They have been implicated in various diseases, such as diabetes, cancer, and neurodegenerative disorders.
