Yield	Reaction Conditions	Operation in experiment
82%	Stage #1: 2,3,4-trichloroaniline With hydrogenchloride; sodium nitrite In water at -5 - 5℃; for 1h; Stage #2: With copper(l) chloride In water at 50 - 80℃; for 1h;	3 Preparation of intermediate 1,2,3,4-tetrachlorobenzene (IV) In a 500 ml bottle 2,3,4-trichloroaniline 10 g (0.051 mol) and concentrated hydrochloric acid 21 g were added. The temperature was controlled to -5-5°C by adding 4 g of aqueous solution of sodium nitrite. After completion of addition, the mixture was insulated for 1 hour. In another 1000 ml bottle 50 g concentrated hydrochloric acid and 6 g cuprous chloride were added at 50°C and the preceding nitrosation solution was added, and heated to 80°C for 1 hour. Then the mixture was cooled to 30 ° C, extracted with dichloroethane, and evaporated to dryness to obtain 1,2,3,4-tetrachlorobenzene 9 g, GC analysis (more than 98%) yield of 82%.
