Yield:328-84-7 82.46% ,50594-82-6 5.25% ,56148-83-5 12.29%
Reaction Conditions:
with sulfuric acid;chlorine;aluminum (III) chloride;iron at 110;Product distribution / selectivity;
Steps:
1
Into a 1000 ml 4-neck flask add p-chloro trifluoromethyl benzene 1000 g, metal powdered iron 6 g, and anhydrous aluminum chloride 10 g, start agitation, heat the mixed solution to 100° C., then slowly feed concentrated sulfuric acid-dried chlorine 1028 g under reaction temperature 110° C., take sample, make GC analysis and trace to judge the reaction end point, lower the temperature, discharge the products, and obtain mixed solution of chlorides. The mixed solution contains 82.46% the 3,4-dichlorotrifluoromethyl benzene, 5.25% the 3,4,5-trichloro trifluoromethyl benzene and 12.29% 2,4,5-trichloro trifluoromethyl benzene and polychlorides.
