Introduction;
Bisphenol AF, abbreviated as BPAF, is slightly soluble in carbon tetrachloride, sparingly soluble in water, and readily soluble in organic solvents such as ethanol, acetone, diethyl ether, and toluene, as well as strong alkaline solutions. Bisphenol AF decomposes and burns when heated to 510℃.
Chemical Reactions;
Bisphenol AF dissolves in dilute alkalis to form corresponding metal salts and can undergo nitration, nitrosation, Friedel-Crafts alkyl substitution, halogenation, carboxylation, and esterification reactions. It can condense with acetone to form polyphenols, condense with excess formaldehyde in an alkaline medium to form phenolic resins, and condense with fatty alcohols, epoxy polymers, epichlorohydrin, etc., to form corresponding ethers.
Applications;
Bisphenol AF is mainly used as a vulcanizing agent (crosslinking agent) for fluororubber; over 70% of fluororubber uses the Bisphenol AF vulcanization system. Bisphenol AF can be used as a monomer to synthesize fluorinated polyimides, fluorinated polyesters, fluorinated polyarylethers, fluorinated polyetherketones, fluorinated polycarbonates, fluorinated epoxy resins, fluorinated polyurethanes and other fluorinated polymers. These are used as gas separation membranes, proton exchange membranes, dielectric coatings, optical fiber sheaths, phototube substrates, adhesives, etc., and are widely used in microelectronics, fuel cells, optics, space technology and other fields.
