DICARBOXYLIC ACID Meaning and
Definition
-
Dicarboxylic acid is a type of carboxylic acid compound that contains two carboxyl (-COOH) functional groups. It refers to an organic compound with two carboxyl groups separated by a carbon atom.
The term "dicarboxylic" is derived from the word "di-", which means two, and "carboxylic acid," referring to a class of organic compounds characterized by the presence of one or more carboxyl groups. These acids exhibit distinct chemical properties due to the presence of two carboxyl groups in their molecular structure.
Dicarboxylic acids are commonly found in nature and can be synthesized through various chemical processes. They are often categorized based on the number of carbon atoms in their molecular structure, with examples including oxalic acid (which has two carbon atoms), malonic acid (three carbon atoms), succinic acid (four carbon atoms), and adipic acid (six carbon atoms).
Dicarboxylic acids have a wide range of applications in different industries. Some are widely used as intermediates in the chemical synthesis of pharmaceuticals, polymers, and other organic compounds. They are also utilized as flavoring agents in the food and beverage industry. Additionally, dicarboxylic acids can form salts known as dicarboxylates, which have various industrial uses, including as chelating agents, corrosion inhibitors, and pH regulators.
In summary, a dicarboxylic acid is an organic compound with two carboxyl functional groups, making it distinct within the broader category of carboxylic acids.
Etymology of DICARBOXYLIC ACID
The word "dicarboxylic acid" has a straightforward etymology:
1. "Di-" is a prefix derived from the Greek word "dis", which means "two" or "twice". It is used to indicate that there are two carboxyl (COOH) functional groups present in the molecule.
2. "Carboxyl" comes from the combination of the word "carbonyl" and the Greek word "oxys", meaning "acid" or "sharp". A carboxyl group consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-OH).
3. "Acid" originates from the Latin term "acidus", which means "sour". It is used to describe a substance that donates protons (H+) and lowers the pH when dissolved in water.
