YieldReaction ConditionsOperation in experiment
99.49% With chlorine; at 60℃; under 760.051 Torr; for 1.66667h;Irradiation; EXAMPLE 2 [0039] First, 600.01 g (3.37 mole) of TFPX is added into a glass reactor and stirred evenly by a stirrer. Subsequently, TFPX in the glass reactor is heated to 60 C. by hot water (jacket heating) and irradiated with a mercury-vapor lamp (400 W). [0040] At this time, slightly excessive Cl2 (about 600 g; 8.43 mole) is continuously introduced into the glass reactor so as to perform chlorination. During the reaction the pressure in the glass reactor is kept slightly higher than 1 atm (about 1.01 atm), and the reaction is maintained for 100 minutes to obtain a light yellow liquid. [0041] After the steps as described above, the light yellow liquid is analyzed by GC. According to the results of GC analysis, the formation of CFB is confirmed, and the purity of CFB is 99.49%.
With chlorine; dibenzoyl peroxide; In tetrachloromethane; at 80℃; for 9h; Add 50g of <strong>[369-54-0]1,4-bis(difluoromethyl)benzene</strong> to a three-necked flask,500mL of carbon tetrachloride, 7.5g of benzoyl peroxide,After replacing the air, the chlorine gas is blown in,The reaction was stirred at 80 C for 9 h. After TLC monitoring reaction is completed,Nitrogen gas dissolved in the reaction liquid was bubbled in.After the gas exchange is completed, the organic phase is washed with water until neutral.The organic phase is washed with a sodium thiosulfate solution to remove benzoyl peroxide.To the starch potassium iodide test paper does not change color. The organic phase was separated and washed 3 times with water.The organic phase was dried over anhydrous magnesium sulfate. Anhydrous magnesium sulfate was removed by filtration.The solvent was evaporated under reduced pressure to give 103.75 g of colorless oil.Crude product of 1,4-bis(chlorodifluoromethyl)benzene product.

YieldReaction ConditionsOperation in experiment
With chlorine; In tetrachloromethane; EXAMPLE 2 Preparation of dichloro-tetrafluoro-p-xylene: A solution of 10.7 grams ("g") of α,α,α',α'-tetra-fluoro-p-xylene in 100 milliliters ("ml") of carbon tetrachloride is irradiated with an ultraviolet lamp. The solution is maintained at the reflux temperature of the solvent by the heat of the ultraviolet lamp. Chlorine is passed into the solution until the color of the chlorine remains in solution, i.e., about 9g of chlorine. Irradiation is continued for an additional 30 minutes. The excess chlorine is purged from the solution by a stream of argon. Distillation of the reaction solution yields 11.6g of α,α'-dichloro-<strong>[369-54-0]α,α,α',α'-tetrafluoro-p-xylene</strong> having a boiling point of 86-90 C. at 34 millimeters Hg.
