white to slightly yellow crystalline powder | [Uses]
4,4′-Difluorobenzophenone has been used in the study of thermal stability, water uptake and proton conductivity of carboxylated, carboxylated/sulfonated, and crosslinked membranes. | [Synthesis Reference(s)]
Journal of the American Chemical Society, 90, p. 540, 1968 DOI: 10.1021/ja01004a087 | [General Description]
4,4′-Difluorobenzophenone is typically used as a starting material for the preparation of polyetheretherketone (PEEK) polymer, a high-temperature thermoplastic, which finds wide use in dentistry as well as in automotive, oil industries, etc. | [Synthesis]
①Mix 200g of fluorobenzene with 65g of anhydrous aluminum trichloride, cool to 0-5℃, add 100g of p-fluorotrichloromethylbenzene dropwise reaction for 20min, get 4,4'-difluorophenyl dichloromethane; ②Add 4,4'-difluorophenyl dichloromethane to 600g |
