pyromelltic acid dianhydride - Introduction
pyromelltic acid dianhydride(pyromellitic acid dianhydride) is an organic compound with the chemical formula C10H2O6. It is white crystalline or powdery, insoluble in water at room temperature, but soluble in organic solvents such as ethanol and xylene.
pyromelltic acid dianhydrides are widely used in the chemical industry and materials science. It is commonly used as a raw material for synthetic resins such as high-performance polyimides, polyamides and polyesters. These synthetic resins have excellent thermal stability, mechanical strength and electrical insulation properties, and are commonly used in the preparation of high-temperature plastics, coatings, adhesives and electronic devices.
The preparation of pyromelltic acid dianhydride is mainly obtained by The pyrolysis reaction of pyromellitic acid. Pyromellitic acid is heated to a high temperature, and the two carboxylic acid groups (COOH) in it will be dehydrated and condensed to form an anhydride ring, thereby producing pyromeltic acid dianhydride.
When using pyromelltic acid dianhydride, you need to pay attention to its safety. It is irritating and may have an irritating effect on the eyes and skin. Wear appropriate protective gloves and glasses to avoid contact with skin and eyes. At the same time, it should be operated in a well-ventilated environment to avoid inhaling its dust. In case of inhalation or contact, rinse immediately with water and seek medical help.
