Resolve Resolution of 2,3-Difluorophenol CAS NO. 6418-38-8

Using 2,3,4-trifluoroaniline as raw material, through two steps of diazotization and hydrolysis, and then adopting appropriate treatment methods to obtain 2,3-difluorophenol, the synthesis conditions were studied. The experimental results show that: when diazotization The reaction temperature of preparing trifluoroaniline sulfate and adding sodium nitrite dropwise should be controlled at about 55 ℃ and 15℃, respectively; the optimal hydrolysis temperature of diazonium salt is 50-55 ℃, and the mass fraction of 0.5 is added when reacting with hypophosphorous acid. % catalyst, the highest yield can be obtained. The obtained product has a melting point of 33.8~35.6 °C, a purity of ≥99.6%, and a yield of ≥65%.
