2,5-Furandicarboxylic acid, referred to as FDCA, is an organic compound composed of a furan ring and two carboxyl groups. It is soluble in water under alkaline conditions and is a white powdery solid under acidic conditions. CAS number: 3238-40-2, molecular formula: C6H4O5, molecular weight: 156.09, EINECS number: 221-800-8, melting point>310°C (decomposition).
Good thermal stability
The furan ring structure of 2,5-Furandicarboxylic Acid is an oxygen-containing five-membered aromatic ring. Its conjugated electron system enhances the thermal stability of the molecule, allowing it to withstand thermal decomposition temperatures of up to 310°C.
High reactivity
The two carboxyl groups (–COOH) in the molecule are active and have strong nucleophilicity, and can undergo polycondensation reactions with a variety of alcohols to form polyester bonds. The electron cloud of the furan ring is evenly distributed, which further promotes the chemical reactivity of the carboxyl group and improves the polymerization efficiency so that the reaction conversion rate of the product reaches more than 98%.
Good optical properties
The conjugated system of the furan ring enables 2,5-Furandicarboxylic Acid to effectively absorb ultraviolet rays in the 200-300 nanometer band, making it suitable for optical coatings and packaging materials.
- Bio-based polyester production: used as a renewable alternative to terephthalic acid to prepare polyethylene terephthalate.
- Biodegradable plastics: used to make environmentally friendly degradable plastic materials.
- Semi-aromatic nylon synthesis: used as an important monomer in the production of high-performance nylon.
- Unsaturated resin manufacturing: used as a key raw material for resin synthesis to improve the corrosion resistance of materials.
- Polymer modifiers: improve the performance of petroleum-based polymers.
To ensure product quality, it is recommended that 2,5-furandicarboxylic acid be stored in a dry, cool, ventilated environment to avoid moisture and high temperature. It should be sealed during transportation to prevent moisture absorption and agglomeration to ensure a stable use effect.
