1107-00-2 Usage

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).

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.

Physical properties

Beige crystal

Uses

Different sources of media describe the Uses of 1107-00-2 differently. You can refer to the following data:
1. 4,4'-(hexafluoroisopropylidene)diphthalic anhydride be used for the preparation of a polyimide material.
2. 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

Check Digit Verification of cas no

The CAS Registry Mumber 1107-00-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1107-00:
(6*1)+(5*1)+(4*0)+(3*7)+(2*0)+(1*0)=32
32 % 10 = 2
So 1107-00-2 is a valid CAS Registry Number.

A new synthetic route of 4,4′-hexafluoroisopropylidene-2, 2-bis-(phthalic acid anhydride) and characterization of 4,4′-hexafluoroisopropylidene-2,2-bis-(phthalic acid anhydride)-containing polyimides

Zhu, Shi-Zheng,Zhao, Jing-Wei,Zhang, Yun-Xiang

, p. 221 - 225 (2003)

The title product 4,4′-hexafluoroisopropylidene-2,2-bis-(phthalic acid anhydride) was prepared from hexafluoroacetone and o-xylene as the starting materials by condensation, oxidation and dehydration three-step reaction sequence. It reacted with diamines in DMF or xylene to give polyimides by condensation polymerization. Thermal and viscosity analyses show that these polyimides have lower molecular weight but excellent thermal stability.

Synthesis process of 4, 4-(hexafluoroisopropenyl) diphthalic anhydride

-

, (2020/09/09)

The invention belongs to the technical field of synthesis of 4, 4-(hexafluoroisopropenyl) diphthalic anhydride, in particular to a synthesis process of 4, 4-(hexafluoroisopropenyl) diphthalic anhydride. The synthesis process has the advantages of easy separation of intermediate products, high yield, less waste and good economic benefit, adopts a mixed solvent of long-chain alcohol and ester, reduces the solubility of the product, is beneficial to product separation, and has higher yield. Besides, the Pd/C catalyst is pretreated, a proper amount of sulfide is added for pretreatment, the sulfurpoisoning resistance of the catalyst is improved, the service life of the catalyst is prolonged, and the application frequency of the catalyst is increased; because nitro compounds contain trace amount of sulfides such as sulfuric acid and like, catalyst is easily poisoned. In the step 2, an alumina-silica gel catalyst is added so that 2, 2-bis (3-amino-4-hydroxyphenyl) molecules can be adsorbed on the surface of the catalyst in a flat shape, hydroxyl is closer to the surface of the catalyst, and the amination reaction of hydroxyl is facilitated; in the step 4, a small amount of urea is addedin the cyanolysis reaction to prevent diazonium salt from being oxidized, becoming tar and other side reactions.
