≥98.5% 1,2,3,4-Tetrafluorobenzene CAS No.: 551-62-2

C₆H₂F₄

CAS No.: 551-62-2

product-714-755

Synthesis：

一：Using phthalic anhydride as the first ingredient: This procedure typically entails the following actions: Phthalic anhydride first produces chlorophthalic anhydride by a chlorination reaction, and then it interacts with aniline to produce an imine molecule. Following the substitution of potassium fluoride for the chlorine on the benzene ring, 1,2,3,4-tetrafluorobenzene is obtained by hydrolysis and decarboxylation processes.‌

二：Considering 2,3,4-trifluoroaniline as the initial substance: The following steps are part of this method: 2,3,4-trifluoroaniline first forms a diazonium salt by a diazotization process, and then it combines with fluoroboric acid to generate a diazonium salt of fluoboric acid. Lastly, 1,2,3,4-tetrafluorobenzene is obtained by a high-temperature thermal breakdown reaction.‌

High-performance battery materials and electrolytes can be made with 1,2,3,4-Tetrafluorobenzene to increase the energy density and cycle stability of batteries.‌
