| Item | Details |
|---|---|
| English Name | 2,5-Furandicarboxylic Acid (FDCA) |
| Chinese Name | Er Wu Fu Nan Er Jia Suan (2,5-Furandicarboxylic Acid) |
| CAS No. | 3238-40-2 |
| Molecular Formula | C?H?O? |
| Molecular Weight | 156.09 g/mol |
| Source | from factory East Chemsources - best price |
| Chemical Classification | Bio-based platform chemical; aromatic dicarboxylic acid |
| Appearance (General) | Off-white to pale yellow crystalline powder |
| Property | Value | Test Method |
|---|---|---|
| Melting Point | 342–348 °C (decomposes) | ASTM D3418 |
| Boiling Point | Decomposes before boiling | — |
| Density (25 °C) | 1.68 g/cm³ (crystalline) | Pycnometer method |
| Solubility | - Slightly soluble in water (≈0.1 g/100 mL at 25 °C)- Soluble in dimethyl sulfoxide (DMSO), N,N-dimethylformamide (DMF), and hot ethanol- Insoluble in non-polar solvents (hexane, toluene) | Gravimetric method |
| Sublimation Temperature | ≈280 °C (under reduced pressure) | — |
| Crystal Structure | Monoclinic | X-ray diffraction |
| Bulk Density | 0.5–0.7 g/cm³ (powder form) | ASTM D1895 |
| Property | Description |
|---|---|
| Reactivity | - Typical dicarboxylic acid reactivity: undergoes esterification, amidation, and polycondensation reactions- Reacts with diols (e.g., ethylene glycol) to form polyesters (e.g., PEF: Polyethylene furanoate)- Stable under ambient conditions; decomposes at high temperatures (>340 °C) to form CO? and furan derivatives |
| Stability | - Stable in dry, cool environments- Hygroscopic; absorbs moisture to form clumps (does not affect chemical purity)- Avoid contact with strong oxidizing agents and strong bases |
| Corrosivity | Non-corrosive to most metals (stainless steel, glass) under normal conditions; may react with alkaline metals (e.g., sodium) |
| Biodegradability | Bio-based precursor (derived from fructose, glucose, or lignocellulosic biomass); end products (e.g., PEF) exhibit better biodegradability than petroleum-based polyesters (e.g., PET) |
| Grade Type | Purity (Min.) | Moisture (Max.) | Ash Content (Max.) | Heavy Metals (Max.) | Color (APHA) (Max.) |
|---|---|---|---|---|---|
| Industrial Grade | 99.0% | 0.5% | 0.1% | 10 ppm | 50 |
| Pharmaceutical Grade | 99.5% | 0.2% | 0.05% | 5 ppm | 30 |
| Research Grade | 99.8% | 0.1% | 0.02% | 1 ppm | 20 |
| Item | Requirements |
