| purpose | (1) epoxy resin with bisphenol F as the raw material of epoxy resin and bisphenol A as the raw material of epoxy resin, low viscosity, good workability and other characteristics, can be applied to solvent-free to ultra-high solids coatings, it can also be applied to the fields of lining materials, floor materials, injection materials, impregnating materials, laminated materials and the like. (2) the polycarbonate resin made of bisphenol F and phosgene is soluble in low boiling point organic solvents such as dichloromethane, has low softening point and good processability, the use of stretchability is suitable for the production of a molding material, a thin film, or the like, even when a very large amount of damage is encountered. (3) polyester resin bisphenol F and epoxy alkane addition of biphenyl diol, and dibasic acid reaction of resin, low viscosity, mechanical properties and chemical properties are excellent, it is particularly suitable for the manufacture of corrosion-resistant materials. Bisphenol F can also be used to produce oil-soluble phenolic resins, flame retardants, antioxidants and surfactants. applicable processing film, electronic color separation film, laser photo-array film, bright room copy film has a variety of uses: 1. For the manufacture of textile printing and dyeing auxiliaries 2. For the manufacture of heat-sensitive materials 3. For the manufacture of high-performance epoxy resin 4. For the manufacture of high-grade polymers |
| production method | from the reaction of phenol and formaldehyde in acidic medium. The production process of strong inorganic acid (such as sulfuric acid, hydrochloric acid) as catalyst has many shortcomings, such as equipment corrosion, impurities (such as side reaction to produce chloromethyl ether and chloromethyl phenol), separation is difficult. The United States, the company uses phosphoric acid as a catalyst, the product color is good, the output is high. The biggest advantage is the low solubility of phenol in phosphoric acid, which is conducive to product separation and catalyst recycling. The conversion of formaldehyde was 90%,4,4 '-, 2,4-2,2'-isomers in a ratio of 55:37:8. The organic phase is neutralized, filtered and distilled to obtain the product bisphenol F. |
