Phthalic Acid An Overview of CAS 88-99-3 and Its Manufacturers


Phthalic acid, known by its Chemical Abstracts Service (CAS) Registry Number 88-99-3, is an important organic compound that plays a pivotal role in various industrial applications. This diacid, characterized by two carboxylic acid groups (-COOH) attached to a benzene ring, is primarily utilized in the production of phthalate esters, which serve as plasticizers to increase the flexibility and durability of plastics.


Properties and Applications


Phthalic acid has several notable physical and chemical properties. It is a white crystalline solid that is soluble in alcohols, ether, and some organic solvents. Its melting point is approximately 131 °C, and it has a boiling point of around 295 °C. Due to its dual carboxylic acid functionality, phthalic acid can undergo a variety of chemical reactions, making it a versatile compound in synthesis.


The primary applications of phthalic acid include


1. Plasticizers The largest portion of phthalic acid produced globally is converted into phthalate esters, which are essential additives in polyvinyl chloride (PVC) products. These plasticizers enhance the flexibility, transparency, and durability of plastics, making them suitable for a wide range of applications, from flooring and roofing materials to consumer goods.


2. Dyes and Pigments Phthalic acid is also used in the manufacture of dyes and pigments. Its derivatives are incorporated into various coloring agents used in textiles, inks, and coatings.


3. Resins and Coatings Phthalic anhydride, derived from phthalic acid, is a critical precursor in the production of alkyd resins, which are utilized in paints, varnishes, and coatings due to their excellent adhesion and durability.


4. Other Chemical Intermediates Phthalic acid is a raw material for other chemical products, including certain pharmaceuticals and pesticides.
