PHTHALIC ACIDS Meaning and
Definition
-
Phthalic acids are a group of organic compounds that belong to the family of aromatic carboxylic acids. These acids are derived from phthalic anhydride, which is their anhydrous form, by the addition of water or hydroxyl groups. Phthalic acids can exist in isomeric forms, with the two most common isomers being ortho-phthalic acid and iso-phthalic acid.
Ortho-phthalic acid, also known as 1,2-benzenedicarboxylic acid, consists of a benzene ring with two carboxylic acid groups attached at positions 1 and 2. It is a colorless crystalline solid that is insoluble in water but soluble in organic solvents. Ortho-phthalic acid is often used in the production of various polymers, such as polyester resins and polyurethanes.
Iso-phthalic acid, also known as 1,3-benzenedicarboxylic acid, is another isomer of phthalic acid. It has a similar structure to ortho-phthalic acid but with the carboxylic acid groups attached at positions 1 and 3 of the benzene ring. Iso-phthalic acid is commonly used in the production of unsaturated polyester resins, which are widely used in the manufacturing of fiberglass-reinforced plastics.
Phthalic acids as a group are important industrial chemicals and are used extensively in the production of various plastics, resins, and coatings. They play a significant role in the synthesis of products such as polyesters, phthalates, and alkyd resins.

Etymology of PHTHALIC ACIDS
The word "phthalic" in "Phthalic Acids" derives from the term "phthalic anhydride", which is a white crystalline compound used in the production of phthalate esters. "Phthalic" is a back-formation from "phthalic anhydride", coined by combining the names of two related compounds: naphthalene and benzenedicarboxylic acid. The first part of the word, "naphthalene", refers to a hydrocarbon compound with two fused benzene rings, while the second part, "benzenedicarboxylic acid", describes a compound derived from benzene with two carboxylic acid groups attached. These compounds served as the basis for the synthesis of phthalic anhydride, which, in turn, led to the development of phthalic acids.
