Abstract

1,3,5-trichlorobenzene is manufactured by treating 5-chloro-1,3-dinitrobenzene and/or 3,5-dichloronitrobenzene with chlorine, at a temperature from about 200.degree. to 270.degree. C., preferably from about 230.degree. to 250.degree. C. The resulting process product is an intermediate, for example in plant protection.
