1478-61-1 Usage

Description

Hexafluorobisphenol A, also known as ChEBI, is an organofluorine compound derived from bisphenol A with its methyl hydrogens replaced by fluorines. It is characterized by its white to off-white powder appearance and possesses unique chemical properties that make it suitable for various applications.

Uses

1. Used in Fluororubber Industry:
Hexafluorobisphenol A is used as a crosslinking agent for fluororubber, specifically for fluorine rubber vulcanization accelerator FF34. Its application results in fluororubber with high vulcanized permanent deformation resistance and increased tensile strength.
2. Used in Pharmaceutical Industry:
Hexafluorobisphenol A is utilized as a pharmaceutical intermediate due to its unique chemical structure and properties, which can be further modified or combined with other compounds to create new pharmaceutical products.
3. Used in Endocrine Disruption:
Hexafluorobisphenol A acts as an endocrine-disrupting chemical (EDC), activating estrogen through the estrogen receptor ERα. It serves as a full agonist for the estrogen receptor, which can have implications in various biological processes and health effects.

Hazard

Moderately toxic by ingestion.

Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 1478-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1478-61:
(6*1)+(5*4)+(4*7)+(3*8)+(2*6)+(1*1)=91
91 % 10 = 1
So 1478-61-1 is a valid CAS Registry Number.

Organized surface functional groups: Cooperative catalysis via thiol/sulfonic acid pairing

Margelefsky, Eric L.,Zeidan, Ryan K.,Dufaud, Veronique,Davis, Mark E.

, p. 13691 - 13697 (2007)

The synthesis and characterization of heterogeneous catalysts containing surfaces functionalized with discrete pairs of sulfonic acid and thiol groups are reported. A catalyst having acid and thiol groups separated by three carbon atoms is ca. 3 times more active than a material containing randomly distributed acid and thiol groups in the condensation of acetone and phenol to bisphenol A and 14 times more active in the condensation of cyclohexanone and phenol to bisphenol Z. Increasing the acid/thiol distance in the paired materials decreases both the activity and selectivity. This work clearly reveals the importance of nanoscale organization of two disparate functional groups on the surface of heterogeneous catalysts.

Paragraph 0030; 0032; 0033; 0034; 0036; 0037; 0039, (2020/04/17)

The invention provides a synthetic method of hexafluorobisphenol A. The synthetic method comprises the following steps: a) reacting hexachloroacetone with phenol in the presence of a Lewis acid catalyst to obtain hexachlorobisphenol A; and b) carrying out fluorination reaction on the hexachlorobisphenol A and hydrogen fluoride to obtain the hexafluorobisphenol A. According to the method, Lewis acid is used as a catalyst to change the electronic reaction characteristics of the phenol, so that the intermediate hexachlorobisphenol A is obtained from the para-position carbon atom of the phenol andthe carbonyl group of the hexachloroacetone by addition elimination reaction to obtain, but not from the oxygen atom of the phenol and the chlorine atom of the hexachloroacetone by nucleophilic substitution reaction, and the hexafluorobisphenol A is obtained by fluorinating the hexachlorobisphenol A. According to the method, the hexachloroacetone which is low in price, easy to obtain and low in toxicity replaces hexafluoroacetone and hexafluoropropylene oxide to serve as a raw material, the requirement for equipment is low, safe production is facilitated, the production cost is reduced, and anew thought is provided for the synthetic method of the hexafluorobisphenol A. The hexafluorobisphenol A prepared by the method has the advantages of higher yield and higher purity.

Paragraph 0039-0040, (2017/02/09)

The invention provides of a synthesis method of a diaryl hexafluoropropane compound. The method is characterized by comprising the following steps: firstly mixing aromatic hydrocarbon and anhydrous hydrogen fluoride in a reactor, adding a catalyst, and then adding hexafluoropropylene oxide, stirring and heating; removing hydrogen fluoride after the reaction is finished, and refining the rest product to obtain a diaryl hexafluoropropane compound product, wherein the catalyst is one or more of halogenated antimony and halogenated titanium system catalyst. Through the adoption of the method disclosed by the invention, isomerization and condensation reaction with the aromatic hydrocarbon of hexafluoropropylene oxide are realized in a process stage, the process step of the synthesis is reduced, the production cost and the byproduct production are reduced, and the yield of the product is greatly improved.
