| 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride Usage And Synthesis |
| Description | 4,4′-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) is an aromatic organofluorine compound and the dianhydride of 4,4'-(hexafluorisopropylidene)bisphthalic acid (name derived from phthalic acid). It is one of the six most widely used dianhydride monomers, with good balance of mechanical properties and electrical properties, and it is also the most widely used dianhydride monomer in colorless and transparent polyimides. | | Physical properties | Beige crystal | | Uses | 4,4'-(hexafluoroisopropylidene)diphthalic anhydride be used for the preparation of a polyimide material. | | Uses | 4,4'-(Hexafluoroisopropylidene) diphthalic anhydride is involved in the synthesis of polyamides derived from terphenylenes, which is used for gas separation. | | Flammability and Explosibility | Notclassified | | storage | Storage precautions of hexafluoro dianhydride (6FDA) are described as follows: Store in a cool and ventilated warehouse. Keep away from fire and heat source. Packing should be sealed and out of contact with air[18]. It should be stored separately from oxidants, acids and edible chemicals, and must not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that may cause sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials. |
