<p>The invention provides a method for manufacturing bisphenol AF. The method is a manufacturing method using hexafluoroacetone, phenol and hydrogen fluoride, is suitable for a convenient refining method, meanwhile can improve the yield and can reduce the load to the environment. A method for manufacturing 2,2-di(4-hydroxyphenyl)hexafluoropropane is characterized in that: the hexafluoroacetone and the phenol are reacted in the presence of the hydrogen fluoride, wherein when the reaction begins, based on 1 mole of phenol, the hexafluoroacetone is 0.55 to 2 moles and the hydrogen fluoride is 8 to 200 moles.</p> |
