Disclosed herein is a method for producing
2,3,4,5-tetrachlorobenzotrifluoride comprising chlorinating
4-chlorobenzotrifluoride with elemental chlorine, in the presence of from
0.1 to 2% by weight of iron(III) chloride and 0.05 to 0.75% by weight of
aluminum(III) chloride, in each case based on 4-chlorobenzotrifluoride,
where the weight ratio of iron(III) chloride to aluminum(III) chloride is
10:1 to 1:1.
Se divulga adjunto un método para producir 2,3,4,5-tetrachlorobenzotrifluoride que abarca 4-chlorobenzotrifluoride de tratamiento con cloro con clorina elemental, en la presencia de a partir la 0.1 a el 2% en peso de el cloruro del iron(III) y 0.05 a 0.75% en peso de el cloruro del aluminum(III), en cada caso basado en 4-chlorobenzotrifluoride, donde está 10:1 a 1:1 el cociente del peso del cloruro del iron(III) al cloruro del aluminum(III).
