PHTHALIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Phthalic acid is an aromatic dicarboxylic acid with the chemical formula C8H6O4. It appears as a white crystalline solid and is primarily used as an intermediate in the production of plasticizers, resins, and dyes. Phthalic acid is also employed in the synthesis of pharmaceuticals and as a precursor to phthalic anhydride. It can be obtained through the oxidation of naphthalene or o-xylene. Phthalic acid is moderately toxic and can cause skin and eye irritation upon contact. Inhalation of its dust may lead to respiratory irritation. Proper handling includes the use of protective equipment such as gloves, goggles, and dust masks. It should be stored in a cool, dry place, away from incompatible materials like strong oxidizers. Disposal should follow local regulations to prevent environmental contamination. Phthalic acid is a versatile chemical with significant industrial applications, particularly in the production of high-performance materials.
