Trimellitic Anhydride (TMA), identified by its CAS number 552-30-7, is a valuable chemical intermediate with a distinct set of properties that dictate its industrial applications and handling requirements. As a leading trimellitic anhydride manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of understanding these characteristics to ensure safe and effective utilization. This technical spotlight provides essential information for procurement managers, R&D scientists, and production engineers.

Physically, Trimellitic Anhydride typically presents as a white to off-white flake or crystalline powder. Its melting point is generally in the range of 163-169 °C, and it possesses a boiling point of approximately 390 °C at atmospheric pressure. The density is around 1.54 g/cm³. One of its critical chemical properties is its sensitivity to moisture. TMA readily hydrolyzes in the presence of water, converting into trimellitic acid. This reactivity necessitates careful storage and handling conditions, typically in a cool, dry environment and in tightly sealed containers. For bulk purchasers seeking to buy trimellitic anhydride, understanding these storage requirements is paramount for maintaining product integrity.

Chemically, TMA is an anhydride of a tricarboxylic acid, which makes it a reactive intermediate. It readily reacts with alcohols to form esters, with amines to form amides, and with epoxides to form crosslinked networks. These reactions are fundamental to its applications in polymer synthesis, plasticizer production, and as a curing agent. For instance, its reaction with alcohols forms trimellitate esters, and its reaction with epoxy resins leads to thermoset materials with excellent thermal and chemical resistance. The purity of the trimellitic anhydride, often specified as 95%min or higher, directly influences the efficiency and outcome of these reactions.

Handling Trimellitic Anhydride requires adherence to strict safety protocols. Due to its reactive nature and potential to cause respiratory sensitization, it should be handled in well-ventilated areas, preferably under local exhaust ventilation. Personal protective equipment (PPE) such as gloves, safety goggles, and respiratory protection should always be used. Inhalation of dust or vapors can lead to respiratory irritation and, with repeated exposure, can trigger allergic reactions resembling asthma. Safety Data Sheets (SDS) provided by the CAS 552-30-7 supplier offer detailed information on hazards, first aid measures, and safe handling procedures.

When considering the 'trimellitic anhydride price', it's important to factor in the costs associated with its proper storage and handling. Sourcing from a reputable trimellitic anhydride manufacturer China like NINGBO INNO PHARMCHEM CO.,LTD. ensures that you receive not only a high-quality product but also the necessary technical support and documentation for its safe and effective use. Our commitment is to provide our clients with the best possible product and guidance, facilitating successful integration of TMA into their manufacturing processes.
