Method for synthesizing 1,3-dinitrohalobenzene compound

The invention provides a method for synthesizing a 1,3-dinitrohalobenzene compound. The method comprises the following steps that A) a halogenated benzene compoundand mixed acid of nitric acid and sulfuric acid are subjected to a first nitrification reaction in a first-stage continuous flow microreactor, and oil-water separation is conducted to obtain a mononitrohalobenzene compound and first waste acid; B) the mononitrohalobenzene compound is drained into a second-stage continuous flow microreactor, a second nitrification reaction is conducted with the mixed acid of the nitric acid and the sulfuric acid, a generated nitration mixture is quenched at the outlet of the second-stage continuous flow microreactor, and filtering is conducted to obtain the 1,3-dinitrohalobenzene compound and second waste acid; C) the second waste acid is recycled to the first-stage continuous flow microreactor, a third nitration reaction with the halobenzene compound is carried out, the oil-water separation is conducted to obtain the mononitrohalobenzene compound and third waste acid, and steps B) and C) are repeated; the halobenzene compound has a structure shown in the formula I. The reaction time is short, the waste acid is less, and continuous production is achieved.

Preparation method of 4-(tert-butyl)-1-phenyl-imidazo[4,5,1-kl] phenoxazine
