What is the Molecular Weight of Pyromellitic Acid?
The molecular weight of pyromellitic acid (molecular formula: C₁₀H₆O₈) is 254.15 g/mol
Effect of Pyromellitic Acid Molecular Weight on Application
1. Reaction metering and chemical synthesis efficiency
- Proportion accuracy: Ensure that the reactants are mixed according to the stoichiometric ratio to avoid the formation of by-products and improve product purity.
- Yield Optimization: In polymerization reactions, such as the synthesis of polyimide, molecular weight deviations will lead to uneven polymerization degrees and affect the material's mechanical properties and thermal stability
2. Solubility and processing properties
- Pyromellitic acid is easily soluble in alcohols and slightly soluble in water (solubility is about 1.5 g/100 mL, 20°C), which is related to its molecular weight and polar carboxyl structure
- When preparing plasticizers or coatings, the molecular weight determines its solubility in organic solvents, affecting the stability of the formula and coating performance
- In epoxy curing and powder coatings, its molecular weight affects its reactivity and migration. Moderate molecular weight ensures coating heat resistance (up to 200–250°C) and good surface gloss
