Product Introduction:

Bisphenol AF is also known as hexafluorobisphenol A, 2,2-bis(4-hydroxyphenyl)hexafluoropropane, 2,2-bis(4-hydroxyphenyl)hexafluoropropane, etc., abbreviated as BPAF.

Bisphenol AF (BPAF) is a fluorine-containing organic compound related to bisphenol A, in which two methyl groups are replaced by trifluoromethyl groups.

Bisphenol A (BPA) is a chemical substance added to many commodities, and its impact on health is questionable.

BPA binds to human estrogen-related receptor γ (ERR-γ), and BPAF almost ignores ERR-γ.

In contrast, Hexafluorobisphenol A activates ERR-α and binds and disables ERR-β.

Therefore, more people will use BPAF instead of BPA as a raw material.

The Chemical Properties of Bisphenol AF:

Under normal conditions, it is slightly soluble in carbon tetrachloride, hardly soluble in water, and easily soluble in organic solvents such as ethanol, ether, toluene and strong alkali solutions.

Bisphenol AF can decompose and burn when heated to 510°C.

Bisphenol AF is dissolved in dilute alkali to generate the corresponding metal salt.

Nitration reaction, nitrosation reaction, Friedel-Crafts alkyl substitution reaction, halogenation reaction, carboxylation reaction, esterification reaction can occur.

It can be condensed with acetone to form polyphenol, and with excess formaldehyde in alkaline medium to form phenolic resin, and with fatty alcohol, epoxy polymer, epichlorohydrin, etc. to form corresponding ether.

Product Usage:

Bisphenol AF is mainly used as a vulcanizing agent (crosslinking agent) for fluororubber, and more than 70% of fluororubber uses bisphenol AF vulcanization system.

The fluorine rubber vulcanized (crosslinked) with bisphenol AF has low compression set, excellent processing safety, storage stability, thermal stability and chemical resistance, and high tensile strength and tensile strength.

It vulcanized fluorine rubber is mainly used to make high temperature, oil and medium resistant hoses, tapes, diaphragms and seals.

Its application has expanded from the aerospace field to the automotive, shipbuilding, machinery, chemical, petroleum, light industry and other industrial sectors, especially in the automotive industry, petroleum industry, energy conservation and environmental pollution control and other application fields have developed faster.

Bisphenol AF can be used as a monomer to synthesize fluorinated polyamides, fluorinated polyesters, fluorinated polyaryl ethers, fluorinated polyether ketones, fluorinated polycarbonates, fluorinated epoxy resins, fluorinated polyurethanes and Other fluoropolymers.

Used as gas separation membranes, proton exchange membranes, dielectric coatings, optical fiber jackets, phototube substrates, adhesives, etc.

It is widely used in microelectronics, fuel cell, optics, space technology and other fields.

It modified heterocyclic special polymers can obtain higher thermal stability, oxidation resistance, light transmittance, low dielectric constant and water absorption.

It can also be used as an intermediate in organic synthesis.

Know About the Synthesis Method of Bisphenol AF:

The synthesis method of bisphenol AF includes phenol and hexafluoroacetone catalytic condensation, phenol and hexafluoropropylene oxide catalytic condensation, aniline and hexafluoroacetone condensation, diazotization, hydrolysis, alkylation 4-step synthesis method and bisphenol A low-temperature fluorination method, etc.

There is still great potential for optimizing the production process of bisphenol AF.

Improve the existing synthesis process, select suitable solvents and catalysts, shorten the reaction time, control the side reactions of the system, and reduce the amount of by-products.

Simplifying operations, doing a good job in product refining and recycling of by-products, can save production raw materials, reduce production costs, and protect the ecological environment.

Improving the quality and yield of bisphenol AF is of positive significance for enhancing product competitiveness and can create huge economic and social benefits.

With the research, development and large-scale application of fluorine rubber and fluoropolymers, it is playing an increasingly important role, and the demand continues to grow.

The research and development of bisphenol AF synthesis process, product refining and by-product recovery and treatment are still necessary.

Note: The above process flow is only for readers to understand and learn, the specific operation should be done according to the actual situation
