P-PHENYLENEBIS (TRIMELLITATE ANHYDRIDE) (TAHQ) - Introduction
p-phenylenebis, also known as p-phenylenebis, is an organic compound. The following describes its nature, use, preparation and safety information.
Nature:
p-phenylenebis(trimellitate anhydride) is a white to pale yellow crystalline powder. It has a relatively high melting point at room temperature and is soluble in organic solvents such as dimethylformamide (DMF) and dichloromethane, but insoluble in water. This compound decomposes when heated.
Use:
p-phenylenebis(trimellitate anhydride) is an important chemical raw material and has a wide range of applications in the polymer industry. It can be used as a high performance amide hydrophobic additives, can improve the temperature resistance and mechanical strength of polyamide. In addition, it can also be used to prepare high-performance resins, coatings and adhesives.
Method:
p-phenylenebis(trimellitate anhydride)) can be prepared by the condensation reaction of terephthalic acid and phthalic acid. The specific preparation method can be carried out according to the following steps:
1. Terephthalic acid and phthalic acid are reacted in an appropriate solvent to generate phthalic acid dianhydride.
2. Reacting phthalic acid dianhydride with an appropriate amount of anhydride raw materials to generate p-phenylenebis(trimellitate anhydride)).
3. Crystallization and purification were carried out to obtain the desired product.
Safety Information:
p-phenylenebis(trimellitate anhydride)) dust can cause irritation and allergic reactions, irritating to the skin and eyes. Use and handle with appropriate protective equipment to avoid contact with skin and eyes. Avoid inhaling dust. In use to maintain good ventilation conditions. The safe handling and storage of the substance shall be in accordance with the relevant safe practices. If contact or aspiration occurs, seek medical help immediately.
