Product Informations
 

Phthalic acid is an aromatic dicarboxylic acid with the chemical formula C8H6O4. It is also known as 1,2-benzenedicarboxylic acid. Phthalic acid is a white crystalline solid and is used primarily as a precursor for the production of various chemicals and polymers. 

Chemical Properties: Phthalic acid exists as colorless to white crystals or powder. It has a molecular weight of approximately 166.13 g/mol. It is sparingly soluble in water but soluble in organic solvents such as ethanol and aceton.

Synthesis: Phthalic acid can be synthesized through the catalytic oxidation of ortho-xylene or naphthalen. The process typically involves the use of air or oxygen as the oxidizing agent. The resulting phthalic acid can then be purified and isolated.

Precursor for Chemicals and Polymers: Phthalic acid is primarily used as a precursor for the production of various chemicals and polymers. It is commonly esterified with alcohols to form phthalate esters, which are widely used as plasticizers in the production of flexible polyvinyl chloride (PVC) and other polymers. Phthalic acid and its derivatives are also utilized in the synthesis of dyes, pigments, and pharmaceuticals.

Reactions: Phthalic acid can undergo various chemical reactions due to the presence of carboxylic acid functional groups. It can undergo esterification reactions with alcohols to form phthalate esters. It can also undergo decarboxylation or acid-catalyzed dehydration to produce phthalic anhydrid, which is a more commonly used derivative.
