Phthalic Anhydride (CAS 85-44-9) is a fundamental chemical intermediate with widespread industrial applications. As a responsible supplier, providing comprehensive information on its properties, potential hazards, and safe handling procedures is crucial for our clients. Understanding these aspects ensures efficient and secure utilization of this vital compound in manufacturing processes.

Chemically, Phthalic Anhydride is an organic compound with the formula C8H4O3. It typically presents as a white, crystalline solid, often in flake form. It has a characteristic, acrid, and choking odor. While it has limited solubility in water, it reacts with it, albeit slowly, to form phthalic acid and release heat. This sensitivity to moisture necessitates careful storage in sealed containers, away from humid environments. Its melting point is around 131-134 °C, and it sublimes readily below its boiling point of 284 °C. These physical properties are important considerations for handling and storage.

From a hazard perspective, Phthalic Anhydride is classified as harmful if swallowed and can cause irritation to the skin, eyes, and respiratory tract. Inhalation of dust or vapors can lead to coughing, sneezing, and potentially respiratory sensitization. The substance is combustible, and its dust can form explosive mixtures with air. Therefore, proper ventilation, avoidance of ignition sources, and the use of personal protective equipment (PPE) such as gloves, safety goggles, and respiratory protection are paramount when handling this chemical. Always consult the Safety Data Sheet (SDS) provided by your supplier for detailed hazard information and recommended safety measures.

Safe handling procedures for Phthalic Anhydride include working in well-ventilated areas, preferably under local exhaust ventilation. Minimize dust generation and accumulation. Avoid contact with skin, eyes, and clothing. When transferring the material, especially in large quantities, grounding and bonding equipment to prevent static discharge is recommended. In case of spillage, contain the material and clean it up using appropriate methods that do not generate dust, and dispose of it according to local regulations.

Incompatible materials for Phthalic Anhydride include strong oxidizing agents, strong bases, strong acids, and moisture. Contact with these substances can lead to hazardous reactions, including fire or explosion. As a leading manufacturer and supplier, we prioritize safety and provide our customers with the necessary information to handle Phthalic Anhydride responsibly. If you are looking to buy Phthalic Anhydride, remember to inquire about the SDS and recommended handling guidelines to ensure safe integration into your operations.

Our commitment extends beyond just supplying chemicals; it encompasses ensuring our clients have the knowledge to use them safely and effectively. We encourage all users of Phthalic Anhydride (CAS 85-44-9) to familiarize themselves with its properties and adhere strictly to safety protocols.
