| | 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride Usage And Synthesis |
| Description | 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) is an aromatic organofluorine compound that is utilized as a dianhydride monomer. It is among the most frequently used dianhydride monomers due to its exceptional balance of mechanical and electrical properties. It is particularly prominent in the construction of colorless and transparent polyimides. | | Physical properties | Beige crystal | | Uses | 4,4'-(Hexafluoroisopropylidene) diphthalic anhydride is involved in the synthesis of polyamides derived from terphenylenes, which is used for gas separation. | | Advantages | The 4,4'-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) monomer contains rigid benzene ring groups, and so, the resulting polymer has excellent mechanical properties. 6FDA contained a stable benzene ring and fluorine atoms. Due to the strong electronegativity of the fluorine atoms and the stability of the benzene ring, the produced polycarbonate had better thermal stability[1-2]. | | Precautions | The storage precautions for 6FDA are as follows: The chemical must be stored in a cool and well-ventilated warehouse, away from sources of heat and fire. Proper sealing is required to prevent contact with air, and it should always be kept separate from oxidants, edible chemicals, and acids. The storage area should have explosion-proof lighting and ventilation facilities and must not allow any mechanical equipment or tools that may cause sparks to prevent accidents. Leakage emergency treatment equipment and suitable storage materials must be readily available in the storage area. | | References | [1] Yile Zhang. “Poly(propylene carbonate) networks with excellent properties: Terpolymerization of carbon dioxide, propylene oxide, and 4,4?-(hexafluoroisopropylidene) diphthalic anhydride.” e-Polymers 21 1 (2021): 511–519.
